Top right is Charlotte from Infinite Strattos, Aka bedt girl.

The other two... feel familiar.

I feel like top left was a childhood friend.

Blond short twin tails from very early 2010s...

From the references page, the top right is definitely Charlotte from Infinite Stratos, who I also think is the best girl in there. Top left may be Kureha (the little sister) from Mayo Chiki, but the bottom left I have no idea.
