I'm pretty sure I know almost all of them but I can't tell where they're from, except for number 2.

Then you're doing better than I. There were a couple I simply couldn't place... and I'm really wondering about 4 and 6 that nobody's gotten them thus far...

I actually expected a lot of people to get 6 as it's from a very popular series. #4 was the one I knew nobody would get.
