Well, you don´t go for easy questions do you...
Youkai academy is from what i can gather the only school of its kind, ie one with an aim for youkai to be able to blend in among humans.
IIRC there were a rare few hints that there MAY be other kinds of schools in existance, but that´s about it.
AFAIK, Moka did not attend a school before YA. But it´s years since i watched it. I´ve also been unable to establish when she began wearing the rosario, as recollections in relation to Kokoa shows her as "herself" fairly old, it seems unlikely that she would attend a human school(without the rosario).
And the number of nonhumans is probably whatever you wish. Most of the time the series makes it look like there should be very few, but then occasionally throws something into the mix that suggests much more, so hard to tell.
(and i did try to research this as i´m using RtV as part of a BtVS crossover of mine(Nanoha as primary cross, Karin and Blood+ also part of the background to some extent), but my basic result kept ending up with "uncertain" so i pretty much just went with what made sense for the story)
