Okay, here goes. I got several things wrong last time.
Toward a Typology of Social Stratification Among the Tzenkethi

Position
Ank - One Corliad Ank Zon-B was an astronomer. Ank = something scientific or mathematical? Research? Archivist-scholar?
Bel - Korzenten's two aides, often present when he is, are Velenez Bel Gar-A and Zelent Bel Gar-A. "Gar" is a government policy specialist (explicitly confirmed). These two are called "advisors" to Korzenten but whatever role they play it is not of the Tzel. Extra-governmental, then, with these two however linked to the government. These two are a pair of whatever-Bels-are that serve the Autarch as aides and "advisors". Bodyguards? Military police? Bel is possibly "Goon in Dark Glasses", then.
Dop – Security? A Dop Yov was one of Alizome’s aides when she was serving in the guise of a trade representative on Romulus. Since the other aide was a Nim Gar like Alizome, that leaves this one to be, perhaps, the security agent? Or is Dop something to do with commerce, the gritty economic realities and not the negotiations?
Nim - Trade representative. Explicitly confirmed. When Alizome is serving in her guise as a representative to the Romulans, she and one of her aides are Nim Gar.
Nok - A servant of the Autarch, who seems to announce visitors (the secretary, then) is a Nok Ren-A. Open to speculation what Nok is, but Ren seems easier to define.
Rej - Autarch (or suitable candidate). Note that the Rej is not of the Tzel. (S)he transcends the government.
Ret - Receives and obeys orders from Ter so that tasks are performed. Simple worker, essentially.
Siv - A Siv Vel-A was commanding a Tzenkethi ship. The Federation translated or interpreted Siv as a title-function, so maybe general "Officer"? A Vel might tell us what exactly his officerdom entails. Alternatively, military command, with Vel telling us what he commands?
Tek - Likely one of the science fields. The Tzenkethi running the original wormhole generating station were Tek Lom-As. Possibly physics?
Ter - Leader/order-giver. A Ter Mak is a police commander, a Ter Ata is a maintenance unit leader, etc.
Tor - Special agent to the Autarch.
Tzel - Government.
Ves - One of the scientific fields; possibly military science? See Choska Ves Fel-A, a problem-solver of this scientific category. The wormhole project has passed from Tek Loms to Ves Fels; make of this what you will (though the "Fel" part is easy to understand - she's here to fix the problems they came up against)
Vik - Speaker/negotiator for the Autarch.
Echelon
Ata – Maintenance.
Fel - “Problem solver”. The Tzenkethi have a whole category of people within any given profession who work through problems.
Gar – Government policy specialist. Explicitly confirmed.
Kre – Administrator.
Lom - The Tzenkethi running the original wormhole generating station were Tek Lom-As.
Mak – Enforcer. Da Police.
Ren - A servant of the Autarch, who seems to announce visitors (the secretary, then) is a Nok Ren-A.
Tov - Governing class; government leaders. Members of the Autarch’s advisory body, the Tzelnira, carry the name components “Tzel Tov”.
Vel – See “Siv”.
Yai – Scientist involved with biology; we know that the Yai scientists oversee genetics and breeding matters, so either “biologist” or possibly “geneticist” – it might well require its own category given the importance Tzenkethi place on it.
Yov – see Dop.
Zon - Astronomy, apparently.
