There is no difference between "real crystal" and "nand crystal." It seems like there may have been a typo or misunderstanding in the question. Crystals are naturally occurring solids with a regular repeating pattern, while "nand" does not have a recognized meaning in this context.
No as Crystal Gayle's real name is Brenda Webb, while Dolly Parton's name is her own real name.
You cannot prove a negative. In order to prove that something is NOT real you first have to try to prove that it is real and fail. This has been known since the time of Aristotle. So the only proof that you can have of something not being real is a lack of proof of its existence. Not a convincing argument.
