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.
Many people all around the world play Minecraft. To find friends to play with, you should create a Minecraft blog.

Not quite sure of your question? If you mean how many can play off of one downloaded Minecraft app on one computer, I don't think there is a limit. Every one must have there own account and log into the game when the last person is done playing is all you need to do. Minecraft keeps track of every log in so there's a drop down menu that will show each players account that you just click on. For example, you have one computer and 5 people in your family that want to play Minecraft. All 5 will have to have there own Minecraft account in order to play with their own maps and saves. You just have to take turns.
Yes, actually minecraft first came out on computer
