Apistogramma identification, please!

[grihan]

Hi, a friend bought 5 "Apistogramma norberti" recently. After comparing them with photos from internet, he saw they weren´t Ap. norberti, so we'd like your help to identify them. Probably sp.maulbruter?

Here go some males photos

And now the females (or males too?)

the second pic look like a sp.Mouthbrooder but can't say much about the 1st one.

3rd and 4th one look like males and not females.

I believe that they are all A. sp. Mouthbrooder/Maulbrüter/Breast-band/Brustband. The extensions on the caudal fin (photo 1)are unusually long, however. I also agree with Marvin, they all look like males to me.
