No.
If you are thinking of a mgic square, the answer is NO. The nine numbers sum to 45 so if you have three rows with equal sums, that sum can only be 45/3 = 15. You can have two rows, each adding to 17, and using the digits only once, but you will not use all digits.
There are 9 numbers. Assuming the question refers to a 3x3 "magic" square, the answer is no. The sum of all nine numbers is 36 so each of the 3 rows must sum to 12.
No.
Draw either 3 rows of 5 columns or 5 rows of 3 columns.

Assuming a 3x3 square, yes. If you want to know a solution where all rows, columns and diagonals sum to 15, it is: 2 9 4 7 5 3 6 1 8
If the version of Excel you are using only has 65536 rows, which was the case up to Excel 2003, then you can't add any more rows. From Excel 2007 onwards there are 1048576 rows, so that is what you would need to use.
Some exercises that can be performed using the rows with a cable machine include seated rows, bent-over rows, single-arm rows, and wide-grip rows.
No.
This is a square matrix where the number of rows and the number of columns are equal.
