minecraft shouldn't take more than 1 or 2 gigs of free memory if you are not doing much(example, mining, idling on singleplayer)
If you are on a heavy traffic Minecraft server, or if you have a lot of mods, Minecraft could use from 4 to 10 gigs of free ram.
If you are asking about hard drive, it can be around one half to one gig of hard drive space.
A little bit above 1 GB
Fix your Java, for example if you have a 32bit pc, use 32java, if you have a 64bit pc, use java 64 bit, or clean out your cache and memory, minecraft needs to have good performace and good backup space (~1 GB)
Depends on how much RAM you have if you have a good amount 6 gigabytes or more is pretty good for minecraft than you can search how to dedicate ram to minecraft. Or just watch this video...
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!
12.00 Gb for PC
Gigabytes?! It should NOT be much, unless it is a combination of 1,000s of minecraft mods. Minecraft mods take up very little space. Just be sure to have winrar or 7zip.
Some good mods are Toomanyitems, xray, or the moon mod if you have 1.8. They do not have much GB either. They work better in MyCraft.

As of yet Minecraft is ONLY a download, if your asking how much room it takes up after you download it then it starts around 20 to 30 Mbs then expands upwards to around 400+ megs and after a few months it could get over 1 or 2 gigs with all the different single player saves, mods, screenshots and worlds saves you may have.

16 GB is recommed

12.00 Gb for PC
It depends on the computer, but usually up to 4 GB of memory.
it takes around 189-934gb It can't take that much. Most games for PC nowadays (FPS or RTS) take up from 6GB to >20GB. 934 GB is probably a random number, and as it takes up a LOT of room, PROBABLY isn't how much space any game can take up.
If you are talking about PC then it is usually about 10 to 15 gigabytes.
