Some of my plants & questions (pls advice)

[locopao]

First of all an unknown pepper plant (i got these seeds from a friend, he told me it's a bolivian rainbow... i don't think so. Any idea?)

 
 
 
This one was doing pretty fine but 2-3 days ago started showing some leaf discoloration / deformation

 
 
 
This is a habanero (i think orange)
 

 
 
 
This one is a red fatalii with some leaf deformation, too
 

 
 
And this one is a naga morich. It was almost dead so i did some topping... Still cannot find what is wrong. Please advice:

 
Thanks in advance for your advices

Thanks Prehensile. Looks like, but both plant and pod are too small.
