Black & Rio M.Blue Umbies, need help identifing, sex

[terrors r us]

Hello, I was asked by some members to post some pic`s of my 3 to 5 inch Umbies for type and sex identification.
I have about eight in total (I think) and each pic is of a different Umbie.
They are all in a 600 gallon grow out tank with many other cichlid grow outs.
I am having a hard time in telling some of the Blacks Gorillus apart from the Rio M.Blues.
Especially what I think might be females.
I am also having a hard time in determining the sex of each.
I also have Caquetaia Spectabilis in the mix but don`t need clarification on them.
So please refer to the picture number and say what type and sex you think it is.
Sorry for bad quality pic`s.
Thanks

Last two pic`s have two Umbies in each pic so you could say
Pic 9; Left side blue female and right side black male.
Thanks

Thanks, I sure hope one of the blues is a male.
Also in the last pic 9, there are two umbies, the one on the left is def. a blue but the one on the right looks completely different, but you think they are both blue? I was thinking the one on the right might be a black female?
