The index in your AxesLabel has to be global, since it can't be a local 
variable peculiar to Table, which after all (I think) has a different  
internal name each time the Table is executed.

SetOptions[Plot, AxesLabel :> {"X", y[[k]]}];

y = {"Y1", "Y2"};

Show[GraphicsArray[Table[k = i; Plot[Sin[x], {x, -1, 1}], {i, 2}]]]
