When to use the right "WHAT!?!?" in japanese

[rpgherogaz]

There are many it would seem.

but i can not find anywhere which, in a simple context, tells you when to use which?

Nani?

Nande?

nan desu ka?

and i am sure there are many more!?!?!

So can anyone help me out on anouther question, so far Jpod101 is at 100% on all my questions

I feel i understand doushite? (how,why) as it refers more to an emotion or feeling, rather than something physical? Is that correct? Also is there more ways of saying why??

Arigatou!

Nani is the only word for what. Things like 'nan desu ka' are dependent on speaking style. You'll learn about that very early on, so you're better off just sticking to the lessons.

Nande means why, not what. I'm not sure that there's any big difference between nande, doushite, naze, but I think naze is generally more direct.
