For e.g; imshowpair(Image1,image2); can be use to superimpose 2 images. What if I have 10 images?

You need to be clear as to what you are aiming to do, independent of the method you will use to do it.
The difference of two images is clear and easy to define. As soon as you add a 3rd image this is no longer the case.
How do you mathematically define the difference of 3 images, let alone 10 images?
Once you have answered that then what you want to do is trivial because you don't need imshowpair, you simply apply the maths yourself and use imshow on the compound result.

Average them
sumImage = double(image1)+ double(image2)+ double(image3)+ double(image4) + ...... etc.
meanImage = sumImage / numberOfImages;

It looked like your edges are in different places, so exactly what does the "edge difference" mean? You can just subtract the edge images and that will make sense if the edges are in the same place but just have different strengths, but if they are in different locations, then what does that mean?
If you want to threshold the images and assign each binary image to a different value, then you can simply add them together and apply a colormap with label2rgb().
