In terms of the primary objects of worship being the intermediaries between the gods and the world rather than the true gods themselves, Those sound like the Loa or Orishas of the various small faiths derived from the religion of the Yoruba people of AfricaAnyway, one of the aspects of the 13 Gods, is that they are broad and abstract beings who have a range of servants, most of whom are mortals who were raised up into celestial service for their great acts in life. While clerics (and paladins) may directly venerate one of the 13 gods, they are just as likely to more directly serve one of those lesser beings (many of which have connections to particular locales and/or Peoples). For now I am calling them "Saints" and they are a kind of demi-god - but I would love a better term than "saint" or "demi-god" and I definitely don't like "angel."
Or Rishi, Muni or just add "Sri" to the name. Cool, but maybe strays too far fron tge request in the OP to not tie it too much into an existing RL religion.Or more a more vedic, less christian flavor you could have a bodhisattva
