They are all non-positive rational numbers.

The absolute value of a number may be thought of as its distance from zero. In mathematics, the absolute value of a real number x is the non-negative value of x without regard to its sign.

Hardly. Since rational numbers are the exact opposite of irrational numbers, no number can be both.

Within the set of rational numbers, positives and negatives are considered opposite.

The additive opposite is negative 8 (-8). Absolute values are always positive numbers.

When the numbers are negative

No, they cannot.

Yes, they can. If x is a non-zero rational number then x and -x will have the same absolute value.

Yes. The additive identity is 0.

The answer depends on whether you mean additive opposite or multiplicative opposite. Assuming the former, the sum of the two numbers is zero.

If 2 numbers are different, but have the same absolute value, then one is the opposite of the other. Any number plus its opposite equals zero.

Quite the opposite. All natural numbers are rational. None of them are irrational.
