I mean, Yang didn't know, because she asked Penny how she knew. Ruby's aside suggests she didn't know; both of these characters are established as idiots, albeit the latter more than the former. On the other hand, Penny (...okay, she's a special case) and Sun clocked her within seconds, and Ozpin caught on at some point. So let's move on to everyone else.

In the first three volumes, Blake's ears would frequently move in ways a bow couldn't. The bow is made from a ribbon much thinner than her ears, so presumably hairs stuck out. Also, volume 4 reveals she's the friggin' princess of the largest faunus-majority polity on Remnant.

Even Weiss, nowhere does she say or imply Blake is human, or that she ever thought she was. The two of them argue endlessly on faunus rights, in a way that almost seems to suggest Weiss has already caught on. Team JNPR are told off-screen, and Pyrrha muffles Jaune, but nowhere is it suggested they ever thought otherwise. I suppose it might mean something that team CRDL leaves her alone, or maybe they just thought Velvet the easier target - after all, they don't treat humans much better.

Even Neptune, who was specifically told to pretend not to know Blake was a faunus, says nothing now that she's not wearing her bow. Qrow hasn't said anything, either, talkative as you might expect him to be. I'm about 90% sure Emerald and Mercury, after "the heiress and the bimbo," had nicknamed Blake "the faunus," although they always knew more than they should have.

(Also, apparenlty some volume 1 fans didn't think she was a faunus?  Even though her theme song goes "I'm a faunus / I'm a faunus / I'm saying I'm a faunus.")
