Tamriel_Data adds many more NPC classes to the game. Most of them are identical or nearly identical to classes found in the base game, in order to filter dialogue for provinces other than Morrowind.
The completely new classes have their own sections with information about their specialization, attributes, and skills. Some have a description only viewable through the Construction Set. Descriptions in brackets were added for those without a meaningful description. There is also a link to NPCs with that class in Tamriel_Data's dependent mods, if any exist.
The "base game classes" are listed separately without further details except for the occasional difference in specialization, attribute, or skill. Italics indicate that there is a service variant of the class, or that the differences apply to the service class. Lists of NPCs are linked in parentheses after the class name.

Clever-Men are practioners of the ancient Nordic magical tradition. They act as counsellors to Kings and Jarls in the affairs of magic and the forces of the otherworld. In olden times, they were widely respected and fought alongside the legendary kings and warriors of Skyrim's past. As mages, they are specialized in the various magic schools. In battle, they adorn heavy armor and supply their magical prowess with axe and shield when needed.
"Courtesan" is a fancy word for "prostitue [sic]"
Fishermen catch fish to eat.
Jarls are the second highest ranking title in the hierarchy of Nordic kingdoms, answering only to their King. The Jarl acts as a vassal to the King, but essentially rules a Jarldom of his or her own. Most Jarl titles are heriditary, and as with most Nord nobility, future Jarls are trained from young age in the skills of combat, war and diplomacy.
