If you use Manhattan Heuristic, there is no such thing as 2 squares apart in the x-axis and 2 squares apart in the y-axis as the shapes are all irregular.

If so, then you simply cannot use the manhattan heuristic. I suggest you use straight line distance instead, (the Euclidean Distance described in this link http://theory.stanford.edu/~amitp/GameProgramming/Heuristics.html)
