Might have some luck in /r/whatisthisthing

The one in picture 11 looks very similar to a police cap badge: https://www.pinterest.com/pin/350717889703601604/

6 and 10 look like an officers heer breast eagle, reproduction here: http://www.1944shop.com/contents/en-us/d69.html Several versions of this, here's one that matches 10 a bit better http://www.landser.com/Heer_breast_early.aspx

The medal in 3 is from the 1935 Nuremberg Rally. "Reichsparteitag der Freiheit" or "Rally of Freedom".

4 is a Hitler Youth patch http://www.militarywarehouse.com/NaziRelicPriceGuide4/index.html ( about a quarter of the way down the page)

5 is a Veterans pin badge : http://www.ioffer.com/i/german-wwii-nskov-war-wounded-veterans-pin-pre-1945-493409404

7 is from the National Socialist Womens League (Frauenschaft), the same badge here (use google translate I guess) http://www3.ilch.uminho.pt/kultur/Die%20NS-Frauenschaft.htm or a smaller article here: http://www.ub.uni-heidelberg.de/Englisch/helios/digi/nsfrauenwarte.html

8 are collar tabs, worn like this : http://e-militaria.com/catalog/germany_third_reich/Army_Wehrmacht/uniforms_accessories/zz_tunic_pioneer/collar-tabs.jpg There were a series of these for each part of the army, looks like those ones are for an artillery officer according to this chart: http://www.patchesofpride.com/images/splashpics3/wehrmachtcollartabsCHART.jpg

9 is a clasp from the army, awarded for close combat : http://www.thirdreichmedals.com/armyclose.html

2 are luftwaffe gull wings, they pin to the collar tabs. http://www.wehrmacht-awards.com/forums/showthread.php?t=432027
