1. Is your character classified as human, magic human, or other supernatural creature, and can Molly pick up on this? Magic human. He's a Seer, technically, and Sveta can see this. So Molly can too, if she wants.
2. Would she be able to tell your character's emotions/change in emotions? Quite easily, yup. Unless Sveta teaches him some tricks.
3. If it ever came up, would mind reading/memory alteration be a possibility? Sure.
4. If it ever came up, would a soulgaze be a possibility? sure.

FOR TEPPIC.

1. Is your character classified as human, magic human, or other supernatural creature, and can Molly pick up on this? DEPENDS. In Limbo, he's technically human, borderline magic human. But he's also a former God. And in the event he actually becomes God!Teppic, she could sense he's... a supernatural creature, I suppose. Or just a plain god. ASK MORE IN THE EVENT OF THIS.
2. Would she be able to tell your character's emotions/change in emotions? When he's human!Teppic, yes. If he's God!Teppic, no.
3. If it ever came up, would mind reading/memory alteration be a possibility? I actually am gonna say no on this, if only because jumping into a demi-god's memory might be a SHEER FUCKING MESS.
4. If it ever came up, would a soulgaze be a possibility? See above.

FOR EVERYONE ELSE:

Same as Artyom, except they're all human.
