Two (three after the edit) calls I think; Pink hair in the upper-right-middle is Birdy; post #1373330 and I think fox-ears sketch on the extreme right-middle is Caster-Extra/CCC. I thought the person below-left of Enja might be Black Rose from .hack, or one of her several clones from the other stories, but the facial tattoos don't match.
Directly above professor Layton looks like Asuka. Makes sense since in a waifu pic Rei is there.
