1st, 7th and last cut are in the gengashuu, chould be:
斉藤拓也, 川合彩香, 松本美乃, 中村拓磨, 野田友美, 加藤美穂, 小森高博

Edit: I think at least 0:24 - end is Yoshino Matsumoto
The handwriting on this Uraraka genga (~3 cuts after this clip) looks like Komori to me

Komori correction for reference (2nd pic):

Had another look at the gengashuu and the handwriting for this part looks very different (+ no 2KA credited in the book) I agree that the genga you linked is probably Komori tho so he probably starts right after this
