no you can not
As long as your account ispremium, meaning you paid for your account, you can playMinecraftregardless of how you got it onto your computer.
What do you mean by this? If you simply mean have minecraft on more then one computer then of course you can. As long as you have a valid account you can download minecraft onto any computer.
Minecraft is all about the account you made, you can log into that account on any computer, you are not forced to play it only on the computer that you purchased it on.

There is no way to play Minecraft off of a flash drive but you can transfer it to a computer with no internet by copying the .minecraft folder ( located in C:\Users\User\AppData\Roaming) and the .exe on to a flash drive then dragging those files onto the destination computer in the same location. THis is the closest thing to playing it off a flash drive.
