Yep, they can be negative too :)
Yes, it applies to even multiplication of fractions and rational and irrational numbers.
Fractions help with numbers that are not whole numbers.
You can have algebraic fractions but, even there, the letters do represent numbers; except that their values are indeterminate.
There is no end to the numbers of maths and there are many classifications of numbers, like primes, fractions, even, odd, positive, negative and others.
All fractions are rational numbers.

The terms "odd" and "even" apply to integers (whole numbers), not to decimals or fractions.
Yes.
Even or odd is a property that only integers (the whole numbers, including positives, negatives, and zero) have. We do not call other numbers (fractions, irrational numbers, imaginary numbers, and so on) either even or odd.
Fractions help with numbers that are not whole numbers.
No. All fractions are not whole numbers, but all whole numbers are [improper] fractions (with a denominator of 1).

An ordered pair can contain any valid numbers - integers, fractions, decimals, or even complex numbers.
