I think the male would be called a dalmatian molly, even though he is predominatly black. I'm not sure about the two females though, they both have red eyes too.
Yeah the first picture with the black and white looks like a regular dalmation molly. The other two look like Gold mollies that bred with dalmation mollies. Quite an interesting color.
Best of luck with your search to find the exact name of your mollies!!
