in hindisght From Shadows does allude to the Faunus thing, but not super explicitly (and the main allusions were sung by the male vocalist, who represents Adam, who was openly a Faunus). When initially watching the show I was surprised by that twist.

Weiss' Volume 1 character arc is her ditching her antiquated beliefs of the Faunus, and part of that is discovering that Blake is one. She didn't know.

Penny knew because she has robot abilities, and she tipped off team RWBY. One member of Team RWBY (probably Ruby) told JNPR after that. We have no reason to think that CRDL or other minor teams would know. Neptune is a shitty actor. Antags know because they have ties to the White Fang and Qrow would be told by Ruby.
