There were no real fixed level on which a people were at - they varied up and down a lot depending on the willingness of that particular ethnicity's willingness to fight for the Germans.

For example, Swedes were regarded as prime examples of Aryans until the less than luekwarm response of Sweden to Operation Barbarossa, the German invasion of the Soviet Union and "the crusade against bolchevism" - then the Swedes had been destroyed by social democracy and were a weak and effiminate people.

The muslim Bosniaks and Albanians were allowed to form two SS divisions and were upgraded from Slaviv and Asiatic/Turkic peoples to somehow being descendants from Persian aryans when the Germans spoke of them - something which was reversed when parts of the Albanian division revolted and cut the throats of their German drill instructors.

Nazi viewpoints varied vastly across the races of Europe. Sometimes, like Vonadler mentioned, they'd change specifically due to the actions of the residing country of the race. Nonetheless, racial views were inconsistent.

The Nazi overview of the Latins, chiefly Frenchmen, Spaniards, and Italians, varied. Since the latter two were Fascist states, Nazi view on them was obviously favorable. However, helped by typical French-German animosity and rivalry, the Nazi's saw the French probably lukewarm at best, they didn't consider the French subhuman or inferior, but hardly gave them the respect they deserved.

The Spaniards were described, by Hitler, as "the only Tough Latins", and seemed to favour them above all of the rest of the Latin races. Spanish volunteer divisions participated on the Eastern Front, primarily the Blue Division, where Hitler described the Spanish as almost equal to that of German divisions. Undoubtedly, Nazi view of the Spanish was favorable, both due to Hitlers seeming approval of them, and their current government being Fascist.

Can't speak much for the Italians, however I imagine that the Nazis didn't view the Italians subhumans, just incompetent due to their failure to do, well, anything really, in war on the side of the Axis.

You mentioned the Romanians as Slavs, which is incorrect, Romanians are latins just like the French, Spanish, etc. Romania had a decently large population of Gypsies, which the Nazis prosecuted and hated. Romanians in general, however, weren't directly prosecuted or hated. Nonetheless, Nazi regard for the Romanians was low as the war went on, and continually stripped weapons, tanks, and supplies from Romanian units to arm German divisions, then got mad when the Romanians performed poorly. This was a pattern repeated with other Axis allies too.

The occupied people of the Lowland countries, the Dutch and the Belgians, were viewed fairly well. They weren't considered subhuman, and considered to be somewhat Aryan, especially the Dutch, whose language was similar to German and their traits similar as well. The Dutch were, and are, a tall people (an important aspect of Aryan attributes) with a distinctively Germanic language and culture, and were therefore looked at fairly. Both were considered viable candidates to be Aryans. The Netherlands was however deeply affected by the latter stages of the war, as the Germans continually took supplies and food from the country to feed their own people and troops, and the hunting of Jews was very extensive in both Belgium and the Netherlands.

The Scandinavians, Swedes and Norwegians, were seen as the ideal Aryans, and were therefore regarded very highly. Political situations, however, such as the uncertain response of Sweden to Operation Barbarossa, hurt their reputation, as none of the Scandinavian races were really fond of the Nazi's. The Danes were among the same level as these.

Now, the Slavic races had it much harder. Poles, Czechs, and Slovaks are all Slavic, and the Germans were very harsh with their treatment of them. In the occupied Czech Republic, the Germans planned to eventually either remove the Czechs and replace them with Germans, or ruthlessly Germanize them. In Poland, Poles were murdered and killed alongside their Jewish brethren just for being Slavic. The Germans also planned to do the same in Poland as in the Czech Republic, and replace much of Poland with Germans, especially lands previously held by Prussia or the German Empire. (In fact, in general, the Nazis wanted to deport most, or at least as many as possible, Slavic peoples to Siberia, as the Germans believed they'd win over the USSR. The plan was to ruthlessly Germanize what Slavs could be "saved", and deport the rest to Siberia, and replace them with Germans. This was the driving factor behind the German prosecution and attack on the Slavic people, as the Germans needed to displace them due to their position in the East, which the Nazi's considered to be the "living space" of the German people.) The Slovaks, the only of the three that theoretically fought alongside the Germans, were viewed a bit better, but were nonetheless battered by Nazi opinion. Since the Poles, Czechs, and Slovaks made up a fair portion of the Eastern European population, German oppression of all three was significant. However, this didn't stop the Germans from eventually recruiting Czechs, Slovaks, and even Poles, into their Army, and even the Waffen SS. The most successful Panzer ace in the war, Kurt Knispel, who scored at least 168 confirmed tank kills with potentially as many as 195, was a Sudeten German from the Czech Republic. Yet, since he was from the Czech Republic (and due to his laid back personality and longer har), he was never promoted beyond NCO status. The Russians had it the hardest, since they were both communist and slavic, which made German persecution of them extremelly violent. Much of the death toll for the Holocaust can be attributed to the killing of Russians on the Eastern Front.

I can't speak much for any of the other races. Nazi opinion realy did depend on the position that the country of the race held. While Bulgarians were Slavic, with direct/indirect roots to the Russians, the Nazi's didn't directly prosecute or attack them because they didn't want to war with Bulgaria, one of their few Allies. While the Balkan races were mostly Slavic, Nazi persecution of them was not as severe as that of the Poles and Russians because they partly fell under Italian influence, and because they weren't directly in the way or of high importance, the Germans wanted to settle lands farther North-West from the Balkans. I have no idea what the Nazi's thought of the Hungarians, Portugeese, or Swiss.

after the lost WWI Hungary's partly isolative foreign policy was used to gain political ground and search for new allies. while quitting the League of Nations, Hungary joined the Anticomitern-Pact in february 1939, joined the Axis in november 1940, and declared war on the USSR in juni 1941. Hungary was a German ally, and was on a good way to become a German vassal, but due to its neutral foreign policy and hesitation in war participation was not considered a trustworthy ally. Germany occupied Hungary, and tried to push to the east one last time during WWII.

it was more important to Germany that Hungary ally up with them and not with one of their enemies, than Hungary's actual military contribution to the war. Hungarians were tolerated but due to their non indo-european language could not be scientically considered as aryans. what would happen to them after Hitler's final vicotry? we will never know for sure.

still, in 1935 to suck in its finno-ugric speaking allies (Finland, Estonia, Hungary), Germany changed the term "aryan" in official state documents and used "person with german or similar blood" instead.

Hitler once said "its unforgiven, that the Budapest with its Attila-breed Huns is the most beautiful city along the Danube and not one Niebelung city"

i also read somewhere, that Göring wanted to claim the hungarian throne so desperately, that he let his family-tree "magyarised" what went so succesfull, that he is still considered a 7th degree Árpád descendant. he also dated his own coronation: just after the final victory.
