Is there going to be another uninvited या an uninvited two just with another family या something?

Uhm, probably not.
Anna went back to the ward.
I think that's it.

That would be totally awesome but I don't think so because the movie is an American remake of the korean movie 'Tale Of Two Sisters'

I dunno. but that was a good movie. it made it like rachel was the killer but it was actually anna. woa that was sooo freaky. my mom was like"omigod!" when the father said"wat r u talking about anna alex is deadd" and omigod that was a crazy movie. it was like a surprising mystery movie. *shudders at the thought of anna doing all that*

No I don't think they would need to, and प्रशंसकों would probably not like the idea of a "replacement", या "remake" idk, it was already a remake of the tale of two sisters, so i don't see why they would.
