Peter Hale became a 8 foot tall monster wolf - Talia Hale and her daughter Laura Hale transformed into real wolves.

Details about Malia Tate are unknown beyond the fact that she appears to be Peter's daughter.

Deucalion doesn't transform into a Demon Wolf - there is no such thing as a Demon Wolf. Deucalion's transformation was somewhere between what we normally see when Derek and Scott transform and what Peter became. He became more monstrous without becoming more animal-like.

What they were saying was that Scott could get lost in his transformation and lose control of his actions. He could become murderous like Peter or forget his humanity and become (mentally) an animal like Malia.
