The characters are vaguely something. There is obvious polytheism, but there's also Hell and monotheism (as Lancelot proves says God rather than gods, like others).

The characters are vaguely something as they have churches and priests, yet abandoned temples and mythical creatures, demons, and the like. So, what are the characters........who knows!

The issue with setting thingas apart is when you have immortal sorcerers (which are pretty much what gods are) and noone particularly worships them, then what religion could they possibly hold.

Eric believed in the "Sea Goddess Ursula" who seems real and very powerful, but that's like one in a few. We dob't see worship of Hades, or the Dark One, perhaps Merlin slightly counts, and religion gets to be a touchy subject.

The characters are more like "I know they may exist", but not the religious type. Rumple says religious thing to Cruella, so there must be some religious things in the EF, but we aren't clear as it may be as religiously diverse as our world but we never get specifics. (It's also how some didn't know that Oz existed)

We don't know enough about the Olympians to tell. We will have to see how they separate the Olympians over the other deities and immortal sorcerers.
