Following Onora O'Neill's lead in "Kant on Reason and Religion", you could form this list of attitudes/viewpoints:
- Hope in the possibility of God ("I hope that God is possible").
- Hope in the actuality of God ("I hope that God is real").
- Belief in the possibility of God.
- Belief in the actuality of God.
- Knowledge (claimed) that God is possible.
- Knowledge (claimed) that God is actual.
There's also transtheism to consider, which might situate a Platonic metanarrative about a Form of the Good as the instructor of a Demiurge, say. A latter-day syncretist, John Hicks, speaks of something he denotes by "the Real" in arguably transtheistic terms/for a transtheistic reason.
At any rate, you can then multiply the first six options at least by two to factor in polytheistic options. Although deism and theism are famously distinguished, the abstract basis for their distinction is not the strongest dividing line in the universe (issues arise with demarcating creation from conservation, for example).
If you're aiming for an a priori tabulation of theological descriptions/relations as such, it'll be hard to come up with a plausible target number to check your lists against. For example, suppose you start out with the distinction between creation-from-nothingness, creation-by-emanation, and creation-from-prime-matter. Suppose you also distinguish being uncreated from being uncreatable, and destructible from indestructible, and try to juxtapose all permutations of these factors in constructing your table. I posted just the question of such a table to the Worldbuilding SE quite a while ago, and I don't think anyone came up with a mathematically resolute answer (actually, they closed the question because I had the title as, "How many levels of..." instead of, "How many categories of..." and they thought "levels of divinity" implied subjective assessments of divine glory).
Addendum. Other variables:
- Is God metaphysically simple?
- Is God unchangeable? Similar, but not identical, to the question of whether God is impassable (e.g., God could be changeable, but only by Its own power; or God could be unchanging, but stand in relations of eternal reactivity to other beings).
- Is God good, or perhaps evil (possible overlap/equivalence with misotheism or dystheism)?
- Are human assertions about God directly true, analogically true, or true only when sufficiently negative (in the abstract, not the emotional, sense of negativity or absence)?
This list of four such questions is not complete, mind you, for we also could consider versions of theism that turn on believing in God for intuitive reasons (e.g. Calvinism's sensus divinitatis) vs. a more Biblical kind of reason (the Bible says that natural theology is enough to prove God's existence, that we can infer the Creator from the nature of the creation), and then if arguments are appealed to, there are theistical distinctions between ontological, cosmological, and teleological derivations (and between descriptive vs. prescriptive reasoning for belief or faith in God). And I faintly recall that there are even more other such questions besides (my personal favorite: is the universal transet the divine intellect, or is it a gigantic, lifeless "container"?).
