2: If x is even, True (excludes x = 0)
There's no reason to exclude 0. Zero is definitely divisible by 2;

4: If the ones and tens digits of x are divisible by 4, True
You mean: if the tens and ones digits form a number which is divisible by 4. The number 31,212 is divisible by 4, for example, because the last two digits form a number (12) which is divisible by 4, even though the tens digit and the ones digit are not individually divisible by 4.

5: If the ones digit is a 0 or 5, True (excludes x = 0)
There's no reason to exclude 0. Zero is definitely divisible by 5;

8: If last 3 digits are divisible by 8, True OR If x is divisible by 2 three times, True
Again for clarity - the last three digits should form a number divisible by 8. For example, 85,328 is divisible by 8 because 328 is divisible by 8 (328 = 8*41).

9: If the sum of the digits are 9, True
You mean: If the sum of the digits is a multiple of 9. The sum does not need to equal 9. The number 95,301 is divisible by 9, for example, because the digits add to 18, which is a multiple of 9.

10: If the ones digit is 0, True (excludes x=0)
There's no reason to exclude 0. Zero is definitely divisible by 10;
