We don't know if Nine's arms were bound while she was Phantom. Terumi stabbed her with Ouroboros before throwing her into the Boundary, but I don't think she really died, she was just there until Izanami summoned her back.

Yes, Terumi was placed under a Mind Eater spell before Nine found Takemikazuchi, then he separated his consciousness from Kazuma, who was left unaffected, so Kazuma is the "Yuki Terumi" of the Six Heroes. After the defeat of the Black Beast Trinity lifted the Mind Eater from Terumi, and he got rid of both her and Nine.

I don't think there is any special dialogue, but I don't really watch gameplay videos. I think someone mentioned that Es and Celica feel like they met before.
