Question

'I have all left' and 'I have noting left', are their same means ？

Answer

I have nothing left= all things gone
I have nothing left= I have nothing leftover.  Leftover=remaining 
I have all left= This sentence does not make sense.
You have to say/specify what you have left.  For example you could say, "I have all the food left".

Answer

You can say either

'I have nothing left'

or

'I don't have anything left'.

These two sentences have the same meaning. 'I have all left' doesn't make any sense.
