Hey does davesprite exist in the new earth?? I'm p sure that we saw other sprites so it wouldn't be crazy to assume, right??

Davesprite is dead. If any incarnation of him exists on Earth C it would be in the form of Davepeta who was in the Furthest Ring when they entered so it’s likely they didn’t make it since other characters that where in the same location (namely Vriska) have been shown not to be there.
