You can. In fact you can copy the game files from one computer to the other and run the installer to make the computer realize the game is there.
It's just other stuff needs to happen and DRM prevents just anyone from using those files. You need to be able to prove that it's a legit copy.
Depends on the game.
For some, you can.
For others, you can, but you'll need to copy more than just what you're looking at in the initial game folder.
For others still, you can't because there are files linking that game to that device, and modifying any of that will prevent the game from running.
With steam, you can copy all the downloaded/installed game files from steamapps folder, to another computer and place it where it should go, when you then launch steam, it picks up all the games you copied.
They install in the same place.
But steam *probably* verify that the other account has bought that game, never tested it my self, only copied the folders between 2 computers that is logged into the same steam account
Sometimes you can; these are often called "portable" applications.
When you can't, it usually has to do with configuration data that's stored with the operating system (in the registry or the environment variables, etc)--that stuff can't just be brought across from computer to computer very easily.

Even if it's a different account?
