The monk/blackbelt is always a guy to me. I just don't see a girl wearing just a vest, and I don't think it's buttoned. Also, what FF girl has no hair but a little tail at the end? Okay some puffy spikey brown hair, whatever.

The White mage might be a girl. Or it might be an extremely girly guy. OR it could be Kurama! You know the FF series has a pretty deep connection with girly guys. (I'm looking at you, Kuja!)
