A Latin Square of order 5 is a 5 x 5 square filled with 5 different symbols, each occurring only once in each row and only once in each column.
5.1 Latin Diagonal Squares (5 x 5)
Attachment 3.7.1
shows the 960 ea order 5 Latin Diagonal Squares, which can be found based on the definition formulated above (ref. SudSqr5a).
5.2 Magic Squares, Natural Numbers
(Simple) Magic Square M of order 5 with the integers 1 ... 25 can be written as
M = A + 5 * B + [1]
where the squares A and B contain only the integers 0, 1, 2, 3 and 4.
Based on the 57600 Euler Squares found in Section 5.1 above, 57600 ea (Simple) Magic Squares can be constructed.

which can be filtered from the 161280 Latin Squares found in Section 5.0 above.
Based on this collection 3072 order 5 Associated Magic Squares can be constructed.
Symmetric SemiLatin Squares
Alternatively order 5 Associated Magic Squares M can be constructed based on pairs of Orthogonal Symmetric SemiLatin Squares (A, B), as shown below for the symbols {a_{i}, i = 1 ... 5} and {b_{j}, j = 1 ... 5).
All pairs of the resulting square (A, B) are distinct, as illustrated by following numerical example:

5.2.7 Evaluation of the Results
Following table compares the enumeration results for order 5 Magic Squares (ref. Section 5.8) with the results based on the construction methods described above:
The constructability by means of Orthogonal (Latin Diagonal) Squares can be considered as an additional property.
5.3 Magic Squares, Prime Numbers
When the elements {a_{i}, i = 1 ... 5} and {b_{j}, j = 1 ... 5) of a valid pair of Orthogonal Latin Diagonal Squares (A, B)  as applied in Section 5.2.1 above  comply with following condition:
the resulting square M = A + B will be an order 5 Prime Number Simple or Pan Magic Square.
