None. All counting numbers are even or odd.
All numbers are either odd or even, none are both, so less than 30 there are 29 counting numbers that are either odd or even but not both. (Assuming you mean starting to count with 1.)
1, 3, 5, 7, 9 counting by twos to 99 are the odd numbers. 2, 4, 6, 8, 10 counting by twos to 100 are the even numbers.
Any product of two or more odd numbers that are larger than 1. For example, 33 = 3*11 is odd and composite.
4999 (not counting 1).
None of them. All counting numbers are either odd or even.
None. All counting numbers are even or odd.
The sum of the first 500 odd counting numbers is 250,000.

1, 3, 5, 7, 9 counting by twos to 99 are the odd numbers. 2, 4, 6, 8, 10 counting by twos to 100 are the even numbers.
Only even numbers are divisible by two. If you have an odd number, for example 3, and divide by two, you will get 1 with a remander of 1.
Yes, the factors of all odd numbers are odd numbers.
