Which animes are these five pictures from?

Hi, I'm looking for the names of the animes these characters are from, if any. Thanks!

Edit: I just realized the second is from Clannad. Still need help on the other four though.

#5 is from the Aria franchise (many series out there).

1 seems to be from To Heart.

2 is Nagisa from Clannad.

4 maybe a fanart of Hazuki from Tsukuyomi: Moon Phase
