I tagged a few but I'm not 100% sure about some (I confuse the original 2hu too!) so I'll have to leave the task of completing the tagging to someone else.
I did tagging as best as i could but the one nearest to the bottom left corner of the sign I think is nemuno although it could be sagume without her wing, the other one i had an issue with is the one near momoyo at the bottom of the sign, the closest i can think would be misumaru because the lavender colored shape near the face looks like one of her hair ornaments although i could be wrong so i left that one untagged.
