(1) EVEN----> Numbers that are divisible by 2..... Eg.-- 2,4,6,8,10 etc........ (2) ODD----> Numbers that are not divisible by 2..... Eg.--- 3,5,7,9,11 etc......... (3) PRIME----> Numbers that are divisible only by two digits i.e. 1 and the no. itself..... Eg.---- 2,3,5,7,11 etc....... (4) COMPOSITE----> Numbers that are divisible by more than 2 digits....... Eg.--- 4,6,9 etc...................(5) TWIN - PRIMES----> Primes numbers that have a difference of 2 in their occurrence, i.e. either 2 less or 2 more than another prime number .......... Eg. (41,43); (3,5) etc............ (6) CO- PRIMES------> Any two numbers whose factorization contains only 1 as a common factor........... Eg.----> 21 and 22......21= 1×7×3..... 22= 1×2×11.....Common Factor is 1 , so they are Co- Primes.... etc....

Answer:
even:An even number is an integer that can be divided by two and remain an integer or has no remainder. An integer that is not an even number is an odd number. If an even number is divided by two, the result is another integer. ... Since even numbers are integers, negative numbers can be even.
odd:Odd numbers are whole numbers that cannot be divided exactly into pairs.
prime:the definition of a Prime number is a natural number that can be divided by only two natural numbers: 1 and itself.
composite: whole number that can be made by multiplying other whole numbers. Example: 6 can be made by 2 × 3 so is a composite number.
twin rime number:A twin prime is a prime number that is either 2 less or 2 more than another prime number—for example, either member of the twin prime pair (41, 43). In other words, a twin prime is a prime that has a prime gap of two. ... However, it is unknown whether there are infinitely many twin primes or there is a largest pair.
co-prime numbers:When two numbers have no common factors other than 1. In other words there is no whole number that you could divide them both by exactly (without any remainder).
