I don't know about Tsume, Hige and Toboe but Kiba is voiced par Johnny Yong Bosch ^^

For the others, it doesn't hurt to try searching Wolf's Rain on Wikipedia, it'll usually say who the voice actor is suivant to the character's name :D

Tsume=Crispin Freeman=Itachi
Kiba=Johnny Yong Bosch=Ichigo,Sasori
Hige=Joshua Seth=McIntyre
Toboe=Mona Marshall=Ichigo(Child),Minoru Kokubunji

(I got bored so I put a few other characters the actors play as)
