Do you mean is there a uniqueness of one god compared to another? Possibly having a trait that is not generalized among the Deities?
I don't know who this question is meant to.
In any case, what I mean is that it is the devotee that established his deities' status as gods.
There is no other requisite, not even consistency or coherence of belief.
What is a god? A god is whatever someone finds inspiration in and decides to regard as a god.
It
may be, or be perceived as, a lot of other things as well, of course. On a strictly personal, customized level.
In a way, it is the triumph of henotheism to its supreme degree: god manifests however the devotee chooses to allow itself to.
In another, it is also the triumph of secularism: gods are created by the devotees and have no obvious external existence or meaning.
