Natural numbers are the whole counting numbers from 1 upwards
Yes. Natural numbers are whole numbers starting from 1 and onwards 2, 3, 4.... basically any number you can add 1 to is a natural number
Yes, when you add any group of natural numbers, the sum will also be a natural number.

Natural numbers are actually closed under addition. If you add any two if them, the result will always be another natural number.
Sure there are greater numbers. For example, 4 is greater than 3. If you mean "... no greatest number", the reason is that you can always add one more, and get a number that is even greater. Thus, for example, 10 is not the greatest number, because you can add one and get 11. 11 is not the greatest number either, because you can add one and get 12. Etc.
Any even number can be written in the form 2n for some natural number n.Any odd number can be written as 2n+1 for a natural number nNow add an even to an odd.2n+2n+1=4n+1 which is 2(2n)+1 and this is the form for an odd number.
The set of natural numbers is infinite. It includes all positive integers starting from 1 and continues indefinitely (1, 2, 3, 4, ...). There is no largest natural number, as you can always add one more to any given natural number, demonstrating that the set does not have an upper limit. Thus, the natural numbers are unbounded and infinite.
no..a natural number is a whole number
there is a zero in a natural number.
No, but is a natural number.
Depending on your definition of a natural number, 0 may or may not be a natural number. If you don't think 0 is a natural number, then it will be the only non-natural number that is whole.
A multiple of a natural number should be another natural number.
