A lot of it is definitely Sharue: https://www.furaffinity.net/gallery/sharue/
Probably WhiteKitten commissions, from the looks of the content in the SMB folder. Azirik did the third image in this thread, though.
... You'd know it was Sharue if you looked at the file names, in fact.I recognized her art, but the files are tagged with it as well. It's obscured as "just a name of one of the cubs", but hers is a pretty unique name in the furry-artist biz.
