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, but you wouldn’t see other galaxies that are behind earth from there. The size is always the same (as far as we know) but wich parts of the whole universe fall into your observable universe differs by location.
