i want to know what characters from the image

1. The girl with long black hair that wear black clothes , seems she was wearing dancer clothes(left from Tanjiro from kimetsu no yaiba)
2. The girl from top left, she wear nurse outfit and holding a medical bag

#2 is Yui Kamio from the series Yui Kamio Lets Loose, but she is dressed up in a nurse's costume. The main character has a 'white' and a 'black' version (double personality); this picture is her white version where her hair is tied up. If you look closely behind the nurse's hat you can see her "magical chain" in her hair sticking out.

I'm not 100% about #1, but I think it's the MC from Act-Age dressed up in a dancer costume.
