I have two different photos of lips but they are from the same person and I have created a mask for each of them, how can I match them and get the percentage of matching?

The do not have to be the same image content, but of course the sizes/dimensions need to match. How could it possibly work otherwise? How could you AND images pixel-for-pixel if one image is 30 by 60 and another is 640 by 480? Think it through. If you resize one, is that OK? Why are they different in the first place? Were they not both acquired by the same camera or process?

You can do it number of ways
2. compare the two gray images, just subtract one image from other, see the difference if
image1-imag2=0
then 100% match, otherwise if image1-image2=not zero matrix just add them and find the percentage.
3. Anotherway you can check the custom function here

First you need to perform an image registration, i.e. matching them first before you compare them pixel by pixel remembering that matching never yields a perfect result/match. There is a number of functions available in the Image Processing Toolbox, such as imregister.
