Someone/somebody

Yes, they have the same meaning.

You can say:

There is somebody/someone waiting for you at the snack-bar.

Does anybody/ anyone here speak English?

That's all!!

I see. As far as I understand I should also use anybody/anyone in the sentences like this: "There is not anybody/anyone waiting for me at the snack-bar". Thank you very much!

I Think it is much appropriate to use nobody/noone. "There is nobody/noone waiting for me at the snackbar."

"Have you any idea how much this cost?" "None at all/None whatsoever."

no one pronoun (ALSO nobody)
no person:

"Who was that on the phone?" "No one you would know."
I'd like to go to the concert but no one else (= no other person) wants to.
No-one told me she was ill.
