Everything is the same universe, they are all take place in the same world just over a year or so period. Now if your more asking about watching order that's a bit more complicated, you can either go Anime/Novel (only one major ordering difference between Anime/Novel) release order or you can go timeline order (which isn't recommended for various reasons).
So Bakemono is first? Are they all on the same service?
