-5 is an integer, a rational number (since it can be represented as a fraction of integers) and it's a real number.

It is NOT irrational (since it's rational). It is NOT a natural number since natural numbers are positive whole numbers. Depending on your book's definition, -5 may or may not be in the set of whole numbers. If your book says that whole numbers are the set {..., -3, -2, -1, 0, 1, 2, 3, ...}, then -5 is a whole number. However, if your book says that the set {0, 1, 2, 3, 4, 5, ...} is the set of whole numbers, then -5 is NOT a whole number.
