I am afraid that you are out of luck with your questions.
The list of people who have achieved a given certification is not published, and in fact in some parts of the world (Europe) it would actually be illegal to publish someone's name in such a list without their explicit consent.
The number of people who have achieved a certification could be found at a page on Microsoft's website some years ago, but the page was removed and, as far as I can tell, this information is no longer made public.
