Ah Jop, aside from the Red haired Swordsman, the gender for the lightning user, Durandal user, and Angel isn't known.

P.s. Kiba noted that a certain someone has a similar swordsmanship as him. If the red haired swordsman is Ise's sons then it might mean that Ise asked Kiba to be his son's teacher.
