While it's likely the one wearing Kouya will be the muscle of the team, I feel like this character could be the unexpected tanky and heavy defense type looking at what I assume is a shield on the back of the armor.
As for voices, a comment on Reddit suggests that Ayumu Murase may voice the Suiren wearer and Junya Enoki may voice the Soukyuu wearer, which, judging by the initials that were revealed and tone of the voices, seem very likely. My guess for Kouya and Senkou at the moment are, respectively, Shunsuke Takeuchi and Kentaro Kumagai.
