It is all of these except irrational, because it is rational, meaning it can be written as a fraction.
The only difference between the set of whole numbers and natural numbers is the inclusion of the number zero.
Integers include zero and negative WHOLE numbers.
Real numbers are, depending on your experience, all numbers.
They are NON-real numbers, or IMAGINARY NUMBERS which involve the square root of negative one, but that might not interest you, now.

Natural numbers: integers greater than 0. Example: 1, 2, 3, ...
Irrational numbers: cannot be represented by a fraction. Examples: pi, square root of 2, square root of 3
Whole numbers: same as natural numbers. Sometimes 0 is considered a whole number.
Integer. Anything that is not a fraction or irrational. Examples: ..., -3, -2, -1, 0, 1, 2, 3, ...
Real number: anything that is not imaginary. Includes natural numbers, irrational, whole numbers, and integers. Examples:
-3, -2, -1, 0, 1, 2, 3, pi, square root of 2, square root of 3, 1/2, 2/3, 7/8. Real numbers can be plotted on the Number Line.
Contrast real to imaginary numbers. Imaginary numbers are like the square root of -1. Imaginary numbers cannot be plotted on the Number Line but can be graphed in two-dimensional number space.
97 is a natural number, whole number, integer, and a real number. It is NOT irrational or imaginary.
