My answer:




Not sure how to format this, but from left to right, then top to bottom, the numbers would be:

2, 5, 5, 1

5, 1, 3, 2

2, 3, 3, 5

5, 1, 2, 4

    This was fun!




    For my solution, I started in the four corners and worked my way inwards, ignoring the 1-5 constraint. When I had completed the grid without constraints, I again started in the corners to adjust numbers to fit the constraints until all constraints were satisfied.



    -3- -4- -4- -1-
    13 14 11
    -1- -5- -1- -5-
    11 10 13
    -3- -2- -2- -5-
    11 9 14
    -5- -1- -4- -3-

      Given the multiple possible answers, it is possible to add further restrictions, such as using integers from [2, 5] only (this solution qualifies!)

                This was fun!




                For my solution, I started in the four corners and worked my way inwards, ignoring the 1-5 constraint. When I had completed the grid without constraints, I again started in the corners to adjust numbers to fit the constraints until all constraints were satisfied.
