What is the difference between all those asm versions?
I wanna know so I can decide for wich asm version I would be going for.

different "asm versions" usually means different architectures.

x86 asm is for an x86 processor.
ARM asm is for an ARM processor.
MIPS asm is for a MIPS processor.
etc...

X86 is just 32 bit, no?

The difficulty is that Intel and everyone else refer to their well-known 64-bit architecture through many different names: x86_64, x86-64, x64, IA32-E, Intel 64, AMD64, etc.

Intel's main lines of 32-bit and 64-bit processors use a generally compatible instruction set (x86 instruction sets). 64-bit x86 processors will first run in real mode (16-bit mode with limited memory access), then protected mode if it is asked by the operating system* (32-bit mode with protected memory access and various other niceties), then long mode if it is asked by the operating system (64-bit mode like protected mode).

You can't run 64-bit instructions or use 64-bit registers on a 32-bit system. You can't use 64-bit instructions in an assembler (not assembly language, the assembler) that only works with/has only been allowed to work with 32-bit instructions.

* ("asked by the operating system" = the operating system sets/ORs a bit in one of the processor's control registers)

OK :)

Now my last question is: what is an assembler? What is it used for? Etc.
Isn't a compiler for ASM languages?

The reason that you don't typically call an assembler a "compiler for assembly" is that an assembler maps what you write pretty much 1-to-1 to actual machine code instructions.

As apposed to a higher level language compiler where "a.b.c()" could very well translate into anywhere form 1 to 100's of machine code instructions, you don't know just from looking at the code.

Ah so it also bloats open the memory from the program, variables and such...
Sounds haxy :3

Not so much. It's more a testament to just how much "a()" can do in a higher level language. It could very well burn down your house and format your hard disk in addition to calling the function a.
