Hi and welcome to the forum
You have 3 male honey gouramis, the brightly coloured one in the bottom picture is the dominant male, the others are being picked on and won't show full colour in a tank with a dominant male.
Female honey gouramis that are original wild colour, don't have a black stripe on the anal (bottom) fin, males do.
The following link has more info on them including a picture showing male and female.
