There is Tamrielic, Draconic, Falmeri, Ayleidic, Akaviri, Dunmeri and Dwemeri as far as I know. The Red Guard had their own language when they came from Yokuda (The called themselves Ragada). I would also assume that the Atmorans had their own language when they found Tamriel.

Leaving Nirn, there is also the Daedric and Aedric language. (I think the Eye of Magnus had Aedric runes on it and rune spells are also Aedric)
