Yes, except for one thing: mathematicians are not agreed whether 0 belongs to it.
Yes. Even numbers greater than 100 is a well defined set. (Although it is a set with an infinite number of members)
The set is well defined. Whether or not a given integer belongs to the set of prime numbers is clearly defined even if, for extremely large numbers, it may prove impossible to determine the status of that number.

When the difference between two counting numbers is odd, it implies that one number is odd and the other is even. This is because the difference between an odd and an even number is always odd. As a result, the sum of the two numbers will be odd as well, since adding an odd number to an even number results in an odd sum.
Yes, they ARE.

Because the description which is given is sufficient to decide whether or not any given number is in the set.

Yes it is. Given any number you can decide whether or not it belongs to the set.

Yes, they ARE.
Well, there is a clear definition, and at least in theory you can always determine whether a number is a primer number or not, so I would say, yes.
Prime numbers have only 2 factors and their set is not well defined because they do not follow an orderly mathematical pattern.
Any well-defined set of numbers.
yes
If there exists even one single item for which you cannot say whether it is in the set or not, the set is not well defined.
