Yeah, one of the things I have to keep reminding people is that clerics may be the chosen of a specific deity but unless you're in a very large city you are not generally going to find a temple dedicated to a specific god. Maybe a shrine or special dedication to a specific god here and there, but most lay priests are priests of the entire pantheon.This was also a thing in Ancient Mesopotamia, Ancient Mesoamerica, Ancient Italy, Ancient Celtic Europe, Ancient Japan, Ancient China…
Ancestor Worship, the Divine King or Queen of the City, the God of the Tribe, and genius loci are very very very common in so-called Polytheisms.
Usually it's more that there is the patron deity of the tribe but you recognise a few other deities too as important to offer sacrifices too, and when you're visiting another city, you offer sacrifice to their patron god as well, just in case.
The big shift for monotheisms like Atenism and Judaism were their refusals to offer sacrifices to or recognition of the other nations' deities (including the Egyptian and Roman God-Emperors, when it comes to the Hebrews).
So when you're portraying a Pelor faction, sure, recognise that the Raven Queen exists too (after all, you eventually will die), and maybe make a generous offering to her temple when you visit Nera or Gloomwrought, but otherwise you're not going to spend much effort on her, since she and Pelor aren't closely related. Erathis and Ioun, on the other hand, live in the same divine city as Pelor as co-rulers, so you may be more likely to have a small shrine to each of them off to the side in your Temple of Pelor.
So since I use a pantheon loosely based on Norse mythology for humans someone may pray to Thor for rain, ask for a blessing from Uller when hunting and about to fire an arrow, sacrifice to Odin before battle. In a smaller village or town with multiple races (particularly on trade routes), there may even be nooks for elven or dwarven deities.
