I'll answer for Rei Hino/Sailor Mars now, and Yuna later, for the sake of our thread.
Hypnosis: I'm going to say no on this. Rei's canonically resistant, and Mars is all but immune.
Telepathy: This is a definite no. Rei and Mars both have nearly impenetrable mental defenses, thanks to the Sailor Crystal and her own psychic abilities. Attempts to read her mind will basically hit a mental "wall" and in all likelihood it can be sensed. If there's a reason for a telepathic conversation, a channel can be opened up though. With reason, she'll answer the psychic phone call, as it were.
