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?

Yes, everyone is at the centre of their own observable universe. As far as we can tell, the universe looks to be mostly the same pretty much throughout, so there’s no reason to think that the general shape or density of it would change much depending on where you are.
