you can separate them, Just be Gentle when you do it.
they aren't too big so you shouldn't have too much of a problem.
When you re pot them just bury them up to the lowest set of leaves.

I would just tie it down since this wont stress it much if any.
just do it gradually, Don't bend it completely over or you will be sad when it snaps. TRUST ME I know.
You can also pinch the tops to make it shoot out side branches.
