Somehow I doubt they knew, in "The Next Step", Salem talked about Cinder killing Ozpin like it was a major accomplishment, which we know now isn't the case. If the whole cabal knew that Ozpin could reincarnate, then there'd be no reason to rejoice over his "death" at Beacon. Hence it would be a vain gesture on Salem's part, and I'm pretty sure she's not into vain gestures. She knew Ozpin was still alive, but didn't tell her acolytes because she wanted them to focus on the downfall of Haven. Though now I wonder if any of them will dare take Salem to task for that very large omission she made. I'm certain we'll find out in Volume 6.
