I want to know if the divines and daedra princes do anything on akavir? i think that akatosh may have presence on akavir because didn't dragons originate from akavir and they are all Akatosh children?

Dragons didn't originate on Akavir, though they are found there.

The Divines and Daedra are, more or less, universal. Different cultures perceive them differently, but they're found in various forms throughout. Since Yokuda had them, and Atmora had them, I don't see why Akavir wouldn't.

Akatosh (or some variation of) is on Akavir. He's called Tosh Raka over there.

Dragons didn't originate from Akavir, BTW. They were the original inhabitants of Mundus and Nirn, like the Hist. A bunch of dragons likely came to Tamriel from Akavir, though, due to their enslavement and attempted extermination, and this may have led some people to believe they all came from there.
