I think it's more implied that the Unown are extensions of Arceus, which is why in the Sinjoh Ruins they're summoned to create you one of the Creation Trio. I think it's a hive mind scenario and Arceus is the physical manifestation of that hive mindBecause I suspect Unown are the true creators of the Pokemon universe, and that the inhabitants Sinnoh attributed to Arceus what was actually the Unown's work.
Celebi is weird because while there is an argument for multiple, because its a time traveler and its lifespan is unknown every Celebi that shows up could be the same one. It would certainly explain the deus ex machina at the end of 4Ever if those Celebi were actually part of a causal loop. Any minor visual difference could be easily attributed to the art style
