The observable universe. Does it mean the edge of space where nothing else is? Is it where the universe is currently at in its expansion after the big bang? Or is it just a barrier that our telescopes are yet to look beyond, and there are just more galaxies past it?

It’s the third one, it’s as far as we can see and there’s certainly more galaxies beyond it. If you travelled far away from earth then you would see a different observable universe.
