Did I identify these aircraft correctly? I photographed a couple of aircraft and tried to identify them, but I'm not sure if it's correct. For me, all of them look like an Airbus A320, but I'm really unsure. So which of these aircraft is an Airbus A320 and if not, what's the correct type?

Airbus A320?

Looks like it :) 

Double window exits over the wings, so no A321 or A319 (with a few exceptions such as Easyjet's A319)
