No, twin primes are pairs of prime numbers that have only one number between them which is a composite number. For example, (3, 5) and (11, 13) are twin prime pairs with the composite number 4 and 12 respectively between them.
There are four pairs of twin primes between 2 and 35: (5,7) (11,13) (17,19) (29,31).
Twin primes are pairs of prime numbers that differ from each other by two. 29 and 31 are twin primes.
There are 35 pairs of twin prime numbers totaling 69 numbers (prime number 5 appears twice in the twin pairs) between 0 and 1000.
The 15 twin prime numbers between 1 and 100 are in 8 pairs. The twin prime pairs are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).

No, 21 and 23 are not twin prime numbers. Twin primes are pairs of prime numbers that differ by 2, such as 3 and 5, or 11 and 13.
There are an infinite number of pairs of prime two apart, classified as "twin primes". For lists, see the link.
They are called twin primes and there are thought to be infinitely many such pairs.
