No.
14 and 21
No, the numbers 19, 21, and 23 are not composite numbers. A composite number is a positive integer greater than 1 that has more than two distinct positive divisors. In the case of these numbers, 19 and 23 are prime numbers because they are only divisible by 1 and themselves, while 21 is a composite number because it has divisors other than 1 and itself (3 and 7).

If an odd number has more than two factors then it is a composite number but if it has only two factors then it is a prime number. Although all prime numbers are odd except for 2 many more odd numbers are composite numbers having more than two factors as for example 21 is an odd number whose factors are 1, 3, 7 and 21.

Not necessarily. For example 15 and 16 are composite numbers. They add to 31, which is a prime number. Similarly, the composite numbers 20 and 21 add up to 41, which is a prime number.
21 and 32
19 is prime number. 10, 21 and 62 are composite numbers.
21 is composite as 3 times 7 is 21 31 is prime
Out of those 100 numbers, 21 of them are prime numbers, so the remaining (100 - 21) = 79 are composite.
