One is not considered a Prime number, because a normal prime number only has two divisors, itself and one. But one only has one divisor- one and itself, which is also one. One is a special case, not prime, not composite.
No, it is the multiplicative identity and neither prime or composite. There was a short period in history when some called it prime--but those years are long gone.

Why is one not considered prime?
The number one is not prime because it can only be divided by one number (not too) as itself and 1 are the same number
Why is one not considered a prime number?
One is neither prime nor composite. For a number to be prime, it can only be dividable by 2 numbers. One is only divisible by one number, 1.
Is number 1a prime or composite number?
1 is not considered to be a prime or composite number because it has only one factor which is itself.
What is the lowest prime number 0 1 2 3 4 5?

sometimes zero is considered a prime, but the number two is usually thought the only one.
Can a prime number also be a square number?
No. To be prime it has to be divisible only by itself and one. That means that no numbers multiply to be it. The only possible exception is one. In the math world it may have been decided whether or not one is a prime number, but that is debatable and I'm not aware of the answer. If 1 was considered a prime number, then it would be the only prime square.
What is the concept of prime factorization to explain why 1 is not a prime number?
A prime number has only two factors which are itself and one whereas a composite number has more than two factors and 1 is not considered to be prime or composite because it has only one factor which is itself.
Is 1 a prime no?
1 is not considered to be a prime or composite number.
What is one of the two numbers that are neither prime or composite. and is not a zero?
It is 1 that is not considered to be a prime or a composite number because it has only one factor which is itself
