The most distant galaxies we can see are about 13.8 billion years old, and because of the expansion of the universe they are thought to be about 46 billion light years away, giving an estimated size of the universe of ~93 billion light years in diameter. But if I was in one of those distant galaxies, would I see more galaxies in every direction that are 46 billion light years further out? And wouldn’t this be repeatable forever?

We can’t know, because we’ve never gotten significantly far away from our planet to tell. However, we have no reason to believe that if you went to anywhere in the visible universe that you’d see anything but more universe around you as far as you can see just as we do here.
