15 is a composite number - it can be divided by 3 and 5. 11, 13, 17 and 19 are all prime numbers, not composite.
The number 9 is an example of a number that is both odd and composite. An odd number is one that is not divisible by 2, and a composite number is one that has more than two positive divisors. In the case of 9, its divisors are 1, 3, and 9, making it composite as well as odd. Other examples include 15, 21, and 25.
21 is an odd composite number
An odd number is an integer that is not evenly divisible by 2. A composite number is a positive number that has divisors other than 1 and itself. So any odd number greater than 1 that is not prime would be a composite odd number. For example, 9, 15, 21, and 25 are odd composite number because the are odd and they have divisors. 1, 3, 5, and 7 are not composite because they are only divisible by 1 and themselves.
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. Composites can be either.
81 is an odd composite number.
The number 9 is an example of a number that is both odd and composite. An odd number is one that is not divisible by 2, and a composite number is one that has more than two positive divisors. In the case of 9, its divisors are 1, 3, and 9, making it composite as well as odd. Other examples include 15, 21, and 25.
The smallest number that is both odd and composite is 9, which is divisible by 3. The odd numbers are 1, 3, 5, 7, 9, 11, ..., and 1, 3, 5, and 7 are all prime. It is 9 that is the smallest odd composite number.

Yes
It is a composite odd number
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. Composites can be either.
It is impossible to list the infinite number of composite odd numbers.
