no.

Depends
If you do this on a DAL calculator, squaring -5 that is, you need to use parenthesis or the calculator works out 5^2 and negates it giving -25.
-5 ^2 = -5 x -5, and when we multiply 2 negatives we get a positive so it should be +25

Yes. (-5)^2 = 25, -5^2 = -25.
This may look a little strange, but if you think of "-5" as "-1 * 5" and you remember that multiplication comes after exponentiation, it may make more sense.

Yes.
(-5)^2= 25
-5^2= -25
The first one, you are squaring -5.
For the second one, you are actually squaring 5, and then adding a negative sign.

yes, it's different b/c (-5)^2 is square of negative five, while -5^2 is negative of five squared
if you need to square some negative number, you should but parenthese of the whole negative number, including the sign, not the number only.

Yes.
The first, (-5)(-5) = 25
The second, (-5)(5) = -25
