thise maby sound very silly question but was just wondering
i heard alot of the gods being their own demensions and world and mostly the things we talk to and ashume that we speak to them are mostly just there avatars there avatars also as i understoot corectly the 9 divines cut them self into pieces wich they creeated the mortal plane with
Hold on, by gods do you mean aedra or daedra? The Nine Divines are the Imperial/Nordic compromise that does not accurately represent the aedra, even if it seems to do an ok job so far. Yes, the aedra gave a lot of themselves up in the creation of Mundus, which is what seperates them from daedra. The avatars of the aedra are few and far between, but they are basically the god's will turned into a mortal being or similar metaphysical being. They use them to directly interfere with our world (ie Dagon and Akatosh at the end of the Oblivion main quest)
but is it posible for those gods to real manifestest before us
You can talk to a divine without an avatar, I assume that is what the shrine blessings are. Unless that is just game mechanics. But no, the aedra cannot manifest themselves directly onto Tamriel without an avatar. I'm sure the aedra could affect the mortals somehow, but I'm not entirely certain of a precedent.
If you speak of the daedra, however, that is entirely different story. I assumed since you mentioned the Nine that you meant aedra.
