The Naragi probably aren't related to humans if I had to guess given their tusks and cat-like features. Very distantly related to humans at best.
Airut are likely a big no given how greatly their mouth's structure differs from our own and from most other humanoids we've seen. Little hard to tell beyond that, however, since they cover up so much.
Dagganoth are likely a big no as well. For one, they're reptillian/amphibian (which, much like avian, puts them on a very different path to mammals). For two, their skeletal structure is very different, favoring digitigrade hind legs and an elongated snout. Acknowledging that, it's actually a bit difficult to place them given the apparent influence the queen has on what characteristics manifest in her brood (given the extreme variance in the Kings and sudden appearance of the sentinels).
Fairy Dragons are likely a no. Their origin, like most dragons, lies with Dragonkin experiments on sea creatures and manipulating the products from there (especially since we know fairy dragons and regular dragons are compatible partners). To know more, we'd need to get more lore on their origins.
Ents are sapient mobile trees, putting them in the same boat as Dryads (far more likely a derivative of trees than of humans).
The Tok/Tzhaar originate from the elder kiln and pre-date humans as well. At best, a human once fell or many humans have fallen into the kiln's lava and was 'remembered' by the Tokhaar like all other the other shapes they've remembered. If it weren't for his skeleton nearby, I'd say Perjour would be the most likely human to be acquired by the kiln. With how long the Kiln was lost for and how difficult it was to get there, it could very well be the case that no other humans have been close enough to be added to the Kiln. So it is a big maybe with a heavy leaning towards no and a definite 'could be' if a human ever falls in.
