Jalter Zerker = Zalter and, for Japanese audience, Zeanne/斬ヌ (Slashing Jeanne) because for them Jalter is 邪ンヌ(Evil Jeanne), so Katana-wielding Jeanne = Zeanne.

Red Hare the Horse (Sekitoba/赤兎馬) = Green River the Horse (Midorikawama/緑川馬), because he is voiced by Midorikawa Hikaru, aka Green River Light.

Shi Huandgi = Sailor Mercury

Ryouma & Oryou = the Oreo Duo, a hard black (dragon) biscuit filled with a sweet cream. Something like that
