Nope, since it's all you can eat they don't allow it
Nope.
In my experience they are not as strict about enforcing that you "fiinish your meal" before ordering a new roll. But you certainly cannot take home any leftovers. (I've never witnessed anybody get surcharged for food wastage but that is something that they mention and will explain when they ask if you've ever been there.)
You cannot order a new side/roll until you finish your meal, let alone take food home. It is not a traditional buffet, so you do not have to get up and grab whatever. Rather you order off of a menu about 3, 4, 5 things at a time and then circle back. Everything made to order.
