Yes.
Every irrational number, every rational number which is not an integer and every integer less than 2 falls into this category.
Every positive integer greater than 1 is either prime or composite.

No, since it is not an integer. A prime number has to be an integer. For example, 13 is a prime number, but 13.01 is not. ======================================
we know that integer may be positive or negative and every integer may be prime number or not a prime number, but the common point of these two numbers is that is one factor is common, which is 1.basis of this the smallest division of an integer is 1.
Every integer is a rational number.
True. Thank you. Now, what's your question ?
Every positive integer greater than 1 can be expressed as the product of a unique set of prime factors. The count of these factors is the prime factors number for the number.
Hi... Every integer can be expressed as the product of prime numbers (and these primes are it's factors). Since we can multiply any integer by 2 to create a larger integer which can also be expressed as the product of primes, and this number has more prime factors than the last, we can always get a bigger number with more prime factors. Therefore, there is no definable number with the most primes (much like there is no largest number)!
Yes. 1 is coprime to every integer greater than it.
Yes, a composite number is a positive integer which has a positive divisor other than one or itself. By definition, every integer greater than one is either a prime number or a composite number and since 2 is the only even prime number the result is every number greater than 2 is a composite number
