During the battle of britain, was there fighting in the skies right above major cities?
When a german aircraft was shot down and the crew ejected, what happened when then landed on the ground.
Did they have firearms and would attack UK citizens, Or were there army waiting for them to reach the ground and promptly arrest them?

Yes, there were dogfights all over southern England including over cities.

In general they would be captured by regular army units or members of the Home Guard, though obviously it depended when and where they landed. Any parachuting aircrew could expect a fairly hostile reception as the country was was on alert against German invasion, the danger from airborne troops and Fifth Columnists becoming something of a mania from May 1940, but there wouldn't be much point in German aircrew attacking anyone, there was no chance of them fighting their way to the Channel then over to France. The wartime film Mrs Miniver features the titular character being taken hostage by an armed German pilot, but is not based on an actual incident as far as I'm aware.
There was a case in Kent that has been immortalised as the ['Battle' of Graveney Marsh] (http://spitfiresite.com/2010/10/battle-of-britain-1940-graveney-marsh.html), one version of the story involving the crew of a Junkers 88 using the aircraft's machine guns and exchanging fire with a unit from the London Irish Rifles; an equally (if not more) plausible version is that the crew were using the guns to destroy classified equipment on the aircraft rather than firing on the troops.

u/Bigglesworth_ gave a very good answer and I don't really have anything to add, but I'd like to point out something that's a pet peeve of mine.
In order to eject you need something like this: an ejection seat, a device which actively removes you from the cockpit. The modern ones can even do so when the aircraft is stationary on the ground.
Back in the day there were no ejection seats, they only really started to appear in a meaningful way in the mid-to-late 1940s. Before that the crew would have to bail out: climb out of the aircraft manually, so to speak, and jump. I've written a bit about it here.
