How can I say: I will help you with anything you need. There are several ways to say "anything" right?

Yes, but in your sentence you can translate anything as nenpòt sa, nenpòt kisa, or nenpòt bagay
I will help you with anything you need.
Mwen va ede'w avèk nenpòt sa ou bezwen.
or
M'ap ede'w ak nenpòt sa ou bezwen.

Is this pretty much the translation you had?
