they are called square numbers because, the numbers that are being multiplied by itself(5x5=25)would equal its' sum OR answer. These numbers would be a perfect square.
They can, but they are called imaginary numbers. This is because a "square" of something is the number that, when multiplied by itself, will equal the first number. A negative multiplied by a negative equals a positive, and positives can't turn into negatives on their own, so there are no square roots of negative numbers.
square roots are nombers times themselves
They are called real numbers. Negative square roots must be complex numbers.
No. The square roots of perfect squares are rational.
Rational numbers whose square roots are whole numbers are themselves whole numbers. They are called square numbers, e.g. 1, 4, 9, 16, 25 and so on.

No. The square roots 8 are irrational, as are the square roots of most even numbers.
Every square number (except 1) is composite. Prime numbers only have two factors, one and the numbers themselves. Since square numbers also have at least the square roots as factors, they have to be composite.

Numbers with square roots that are whole numbers
They are called real numbers. Negative square roots must be complex numbers.
No. Lots of square roots are not rational. Only the square roots of perfect square numbers are rational. So for example, the square root of 2 is not rational and the square root of 4 is rational.
No. The square roots of perfect squares are rational.
No, there are no prime numbers that are also square numbers. Prime numbers are only divisible by 1 and themselves, while square numbers have integer square roots. Since the square root of a prime number is not an integer, a prime number cannot be a square number.
The square root of any non-square number is always irrational, so there is no way to use numbers (other than square roots, surds and squares) to show it precisely.
