I believe the actresses in each of the 4 gifs are different, can anyone please ID any of them as well as the video/location?

Thanks in advance!

1: 天音ありす Alice Amane in KTKP-031
2: めぐり Meguri in MEYD-094
4: 多田ひとみ Hitomi Tada in Tokyo Hot k1202

I don't know 3. She's wearing some mascot costume but the only movie I know with such a costume (RCT-594) doesn't have this scene and the girl in that isn't wearing grey underwear.
