So, 9 has a square root which is 3 because 3*3 = 9

Yes and no. It depends on your definition of square root. By the actual one, yes. All non-negative numbers have a square root. That square root might be irrational but it has a square root, nonetheless. 10 isn't a square number because there's no integer that can be squared to make ten but 10 definitely has a square root: 3.16227766....... If by square root you mean an integer square root, then no. If a number has an integer as its square root then you could square that integer to get the number, making it a square number.

What does a non-square root mean?

It doesn't mean anything. If you've actually seen the term used by a mathematician (which I doubt), you might be able to determine from context what it means, but without that context it's pointless to even try."Square root" has a specific meaning, but "non-square root" could mean that the number in question is not a square root (ludicrous... every number is the square root of something), or that it's not the square root of a given number (an almost equally useless concept), or that it's a root of some kind but not a square root (just tell us what kind of root it is. Cube? Fourth?).

What is the square root of a negative number plus the square root of a negative number?

Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)
