Oooohh I'll settle with ESxP for her for now. I haven't seen the fourth season yet.
I also think
Yang is ESFP. At first I thought ENFP - I had seen her typed that way and it kind of made sense - but she's more S like. At least she seems so. She is clearly E and F, and she seems on the Fi-Te axis. So ESFP.
Nora is the ENFP.
Ruby is a clear Fi-dom. I would go for ISFP over INFP, though she may just seem that way because of the fact that she
has to be involved in physical action (because of the situation she's in) rather than actually
being naturally inclined towards action, adventure, living in the moment etc.
Weiss is ESTJ. I saw her typed as ISTJ - she's definitely not that. She is too bossy towards the others - an ISTJ is more quiet, imposes rules in his own territory and gets less in others' business. She's a Te-dom.
Blake... I don't really know... I think she's a Ti-dom, I'd say ISTP, but I don't exclude INTP. I watched the first 3 seasons some time ago and I don't remember that well. I know that, back then, while watching, I narrowed it down to the 2 Ti-dom types, but I don't know if I went any further and now I'm not sure between the two.
Pyrrha is an ENFJ with a strong Se. Why not Fe dom with Si-aux? Because, for example, the ease with which she went "fuck the rules" about Jaune's fraudulent entry in the Beacon Academy, choosing to cover up and help him.
Jaune is, maybe, ESFJ. I'm not really sure. But he's definitely E and F.
Ren... not completely sure, but I say ISTP. I think he's also a Ti-dom (like Blake).
