Magic square: usually a 3x3 magic square contains the numbers 1-9 each once. The example conforms to this additional rule. However the instructions do not seem to require it.
So: are the magic squares supposed to also be regions in which 1-9 each appear once, or can numbers repeat in the magic square as long as the sums along rows, columns and diagonals are equal ?

The answer key for the Killer Pair example sudoku does not follow the rules of the puzzle (R8C6 and R8C7 add up to 10 instead of 11, and R8C7 and R8C8 add up to 11 instead of 6), and the puzzle itself seems to be broken: there is no way to place a 4 in column 6 without breaking the entire puzzle. The puzzle was fixed right as I posted this, funnily enough.

Also, for Diagonal Skyscrapers, how will two of the same number be handled if they are next to each other in the diagonal line? Will the further building be considered as hidden behind the closer building, or will both numbers count towards the total?

Numbers cannot repeat in a magic square.

Two or more buildings of same height diagonally will be treated as one building.
