How about
1 is the odd number out because
It is neither prime nor composite.
It is its own multiplicative inverse.
2 is the odd number out because
It is the only even prime.
You get the same answer whether you add it to itself or multiply it by itself.
3 is the odd number out because
It is the smallest odd prime.
The digital root (sum of all the digits) of any multiple of 3 is divisible by 3.
4 is the odd number out because
It is the smallest composite number.
It is the only number which you can obtain by adding a number to itself and multiplying the number by itself.
5 is the odd number out because
It is the only number whose multiples can have one of only two digits (0 and 5) in the units' place.
It is the only one of the five numbers for which I could not find two reasons.
The last one is a bit shaky, though!
Another possibility:-
It could be 1 because it has only one factor and its value doesn't change when raised to a power.

What is an odd number minus odd number?
All odd numbers are of the form 2n + 1, where n is an integer.So an odd number minus an odd number is (2n+1) - (2m+1) = 2n -2m = 2(n-m). Both n and m are integers, so while we don't know whether n-m is odd or even, we definitely know that it's an integer and that multiplying it by two cannot possibly give an odd number. So an odd number minus an odd number is an even number. For similar reasons, an odd number plus an odd number is also an even number.
