Yes, 5041 and 36.

they are called square numbers because, the numbers that are being multiplied by itself(5x5=25)would equal its' sum OR answer. These numbers would be a perfect square.
Yes as for example: 2+23 = 25 or 2+47 = 49
25 = 9 + 16 There are many more sets like these. This one has the smallest numbers.

Yes, 5041 and 36.
There are 17 such numbers.

16 of them.
18
14
the highest sum of the numbers is 17 and the lowest is 1. The only perfect squares in that range are 1,4,9, and 16. That means the following numbers will work: 10,13.18,22,27,31,36,40,45,54,63,72,79,81,88, and 90; that is 16 numbers
Yes as for example: 2+23 = 25 or 2+47 = 49
Technically 0, 9 and 16 qualify. Add any two together and they still make perfect squares (i.e. numbers whose square roots are integers). I couldn't find any others < 625 or 252 41, 80 and 320 work! ------------------------------------ Also, 17, 32, and 32 and 72, 72, and 217 ...
25 = 9 + 16 There are many more sets like these. This one has the smallest numbers.
