FFI: Warrior of Light
FFII: Leon.
FFIII: Xande.
FFIV: Cecil, Kain, Edge, and YFL.
FFVI: Edgar, Sabin, and Locke.
FFVII: Vincent Valentine is certainly not a bishi. He's a straight shounen. He's the guy so masculine, he can actually seduce a bishi who thinks he's hetero. Top that with the fact VV is a the dark and mysterious version. Dyne's got it. Reeve (the original version), Cid, "non-canon" you can add Angeal Hewley.
FFVIII: Ward, Major Biggs comes across as this though we never see his face.
FFIX: Amaranth, Blanc presumably, Gilgamesh, Marcus, Steiner, probably Black Waltz No.3 if we could see his face, but his attitude is proof enough. True the dwarfish representation available in the game doesn't represent them well, but you can imagine how good they'd look, say, in a big-budget movie.
FFX: Auron, Jecht, Braska, Cid
FFXII: Balthier (duh), Basch, Judge Gabranth, Reddas, Al-Cid, Vossler
FFXIII: Snow
