I heard that The universe is still expanding.. means that at some point there is a place where the universe hasn't reached yet. That place is another dimension or another universe. Thats why the universe is finite in some way but infinite cause is still expanding.

yes and no
(its infinite in 3 dimensions but could be finite in 4
no
There are no "theories", "evidence" or anything else, just that IF they exist it would explain some paradoxes in quantum mechanics

The universe by all observations is infinite. There are multiple theories to the effect of multiple universes but no proof.

Infinite yet bounded - it curves back on itself in a higher dimension.

we don't know, but we think so.
no evidence, but some theorize that there are other universes.
