Roen would fall into the Job category, that of a Paladin. She idolized Sultansworns when she first arrived in Thanalan, and jumped at the first opportunity to train as a Paladin soon as she got to Ul'dah, with hopes of becoming a Sultansworn. But she also has some training in conjury too, so there is a little bit of a class mixed in.
Brynnalia would be a "bard" in that she likes to entertain and sing and a bow is her preferred weapon in battle (so she is not within melee reach), but I don't consider a Bard in terms of how FFXIV defines a Bard.
Raelisanne/Josette is a "scientist" who studies and dabbles in all sorts of things. So she does not have a true Job nor does she fit into a particular Class.
