You might be thinking of relatively prime numbers. Two numbers are considered relatively prime if their GCF is 1. 4 and 9 are relatively prime.
A person unfamiliar with prime numbers could mistake 51, 91, or any other composite number for a prime number if the person did not factor the number to make sure it had no other factors then 1 and itself.
Mathematics, including prime numbers, is discovered, not invented.Systems and methods we use are invented, but concepts of relationships between objects governed by logic, such as the prime numbers are discovered and named. As such, a more appropriate question might be "Who discovered prime numbers?"Many have discovered prime numbers; the first is unknown to mankind.
Search the Internet for a list of prime numbers - the Wikipedia article on prime numbers might list a few. All numbers between 2-100 that are not prime, are composite. (The number is not counted as prime, nor as composite.)

Yes. Just search Google for "list of prime numbers", and you'll get not only that, but much larger lists as well. You might also look at the Wikipedia article on "prime numbers"; this will give you links to lists of prime numbers.
The judge might be mistaken for once.
I might be reading this incorrectly, but it seems to me that I can take two prime numbers, 3 and 3, and make the square number nine out of them. This is also true of all the other prime numbers.

If you multiply two prime numbers, the product (result) will be a composite number, not a prime number. A prime number has exactly two factors, 1 and itself. The product of two prime numbers will have those two numbers as factors, as well. The sum of two prime numbers might be prime if one of those two numbers is 2, the only even prime number, but otherwise it will not be a prime because two odd numbers will have an even sum, which means it is divisible by 2. Examples: 2 + 3 = 5 (prime) 3 + 7 = 10 (not prime) 13 + 17 = 30 (not prime) If you multiply two prime numbers, the sum of the digits of the product might or might not be prime. Examples: 2 x 7 = 14, sum of digits is 5 (prime) 2 x 11 = 22, sum of digits is 4 (not prime) 3 x 5 = 15, sum of digits is 6 (not prime) 3 x 7 = 21, sum of digits is 3 (prime) 5 x 7 = 35, sum of digits is 8 (prime)

A composite number is made up of a product of prime numbers. It might be considered a non-prime number.
