I have about 5 white screens, I know that 2 of them are for iphone 5c, one is 5s and 2 are iphone 5. The problem is they all look identical! how do I tell them apart, are the codes on the cables different?

Rindikulous, take a look at the image. You see the difference in the ribbon cable as well as other differences. Hope this helps, good luck.
