no, but I don't know why. One is not a Prime number and by definition of a perfect number one must be a prime number.

Yes it is. 6 is the first perfect number, 28 is the second perfect number.
True. By definition, a prime number is divisible by one and by itself. Also by definition, a perfect square has at least an additional pair of factors - it's square root. Therefore a prime number could never be a perfect square. One exception that might come to mind in this case is the number one. One however, is not considered a prime number, and thus does not conflict with this rule.
