Yes.
Yes. Multiplication of integers, of rational numbers, of real numbers, and even of complex numbers, is both commutative and associative.
Yes. That means that the product of two whole numbers is defined, and that it is again a whole number.
Yes.

no
Yes.
If you can never, by multiplying two whole numbers, get anything but another whole number back as your answer, then, YES, the set of whole numbers must be closed under multiplication.

Decimal products are numbers that are the result of multiplication procedures and are not whole numbers. Decimal quotients are numbers that are the result of division procedures and are not whole numbers.
If you mean the set of non-negative integers ("whole numbers" is a bit ambiguous in this sense), it is closed under addition and multiplication. If you mean "integers", the set is closed under addition, subtraction, multiplication.
Yes. Multiplication of any real numbers has the associative property: (a x b) x c = a x (b x c)
