Any well-defined set of numbers.
Not including -integers or counting 1000, it would be 999. Counting 1000 it would be, well... 1000
No. The sum as well as product of two even numbers can only be an even number.
Well, for every 10 numbers there are 5 even numbers (2,4,6,8,10). So if you include beginning and ending numbers, the even numbers from from 100 to 150 are:100102104106108110112114116118120122124126128130132134136138140142144146148150
Counting can theoretically continue indefinitely, as numbers are infinite. However, in practical applications, counting typically ends when a specific quantity or range has been reached. For example, when counting objects, the counting ends when all objects have been accounted for. In mathematics, counting can also end when a specific number or pattern is identified.
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.
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.
