Minecraft uses about 500 megabytes of RAM to play, that can vary if you change the settings.
Minecraft's recommended amount of specs is to have at least 1 GB of space, however the absolute bare minimum is 500MB. With 3 - 4GB's, you should be good to play on some higher settings!
You only need one, but you would need lots of DDR3 (RAM), maybe 2+ GB.
The latest version of Minecraft 1.8 (10/24/2014) is under 20 Megabytes but increases in size as you play, the world is infinitely growing as you explore so the size of the game can be quite different for two people.
