Let's do a tally:

Issei Hyoudou- King(fixed)

Grayfia Lucifuge- Queen

Asia Argento- Bishop

Ravel Phenex- Bishop

Xenovia Quarta- Knight(probably a rook in some cases)

Irina Shidou- Knight(probably a bishop in some cases)

Rossweisse- Rook(probably a bishop in some cases)

Bova Tannin- Pawn(3), Rook

Ouryuu Nakiri- Pawn(5), Rook

Elmenheide Karnstein- Pawn(2)

Roygun Belphegor- Rook

Roygun's servants

That's all of the people that are on Issei's team although he would have to change some people out and switch their positions.
