Except for 2, yes. This is the only even prime number.
This is because the definition of a prime number is it can only be made by multiplying by itself and 1. (13 for example can only be made by 1x13, so it's prime)
All even numbers can be multiplied by some number and 2, so they are not prime. (8 for example can be made by 1x8 AND 2x4, so it's not prime)

All prime numbers are odd except the prime number 2 which is even.

No, just because 2 is a prime number. It's the only even number that is prime though.

No, 2 is a prime number. It's only factors are itself and 1. However, no even numbers greater than 2 can be a prime, because they'll always have 2 as a factor.

Other than 2, all prime numbers are odd

Other than 2 and 5, all prime numbers end with 1,3,7, or 9

yes (other than 2) because subsequent non odd numbers (ie even numbers) are all divisable by 2
