So I looked around and it does seem to be real. Roxy and Jake talked to the cast before on their twitters and were excited when HOA won the KCA. Kae has talked to Oliver Biles before on her twitter (who portrayed Giles in Season 2). I can't find much on Claudia besides her MySpace.

I don't know whether they were just extras or if they're going to have a large role in the future.

If you look on IMDB (which is rarely ever reliable), it says that Kae, Claudia, and Roxy were in House of Eclipse. Nothing on Jake though.
