No. 13 and 28 definitely Patchouli (By zooming at 13, could read ,team shanghai alice, project shrine maiden, etc - blurry) (At 28, clues are Patchouli's dress, the vertically striped one, then ribbons at the water red & blue...i think, and i find it rare for her to wear stockings though)
As for 21 and 31, I don't know what to say, hair color is in the way...Flying book, ribbons on hair and socks suggests that she is patchouli though...And book reads "World is mine", idk
