1. Brianna.  Unlike basically everyone else, it seems like she was intended to become a Jedi.  However, if I were actually the Exile, I wouldn't train her.  She focuses too much on combat.  Also, I bet that in about fifty years, being a Jedi historian and all, she's going to become Traya part three. 
2. Mira.  Again, not someone I'd actually train.  She is a very moral person, but that doesn't make a Jedi.  She has a lot of anger in her, and the a77it00d does not befit a Jedi. 
3. Atton.  I wouldn't actually train him either.  In fact, I wouldn't actually train anyone except Mical.  Atton is good at controlling his feelings, but I don't know if he's responsible enough to be a Jedi. 
4. Mical.  He would be first, but unfortunately for him I hate him.  He has Jedi training (to an extent), and he's very peaceful and calm anyway. 
5. Bao-Dur.  He doesn't seem like a Force-sensitive, even if he is.  If the Exile is a wound in the Force, Bao-Dur is a timebomb in the Force.  Sure, he seems all nice now, but the instant someone mentions Mandalorians, he's probably gonna go off, get his face tattooed and get all Darth Maul.
