The first one could be a pure female peacock (though which species would be nearly impossible to tell), as I have seen egg spots remain after heavy hormoning has worn off. If the color is indeed begining to return it could still be a male. Peacock males can take a long time to come back to color after hormones wear off, if if he is in the same tank as the mbuna, might never color up. (peacocks get very stressed by the boisterous mbuna and often won't show any color, even as adults.)
I agree with Kim on the second one.
