Help with some trilobite IDs

Hi. I was wondering if anyone could help me identify these trilobites. Thanks for your help. 

 

The first two are Moroccan trilobites. I think they belong to the genus Calymene, but I am not sure. I have an ID card that says they are from the Ktaoua Group, Anti-Atlas Region, Morocco, Upper Ordovician. Can anyone confirm this? Thanks.

This is another trilobite from Morocco. I think it is Proteus sp., but would like confirmation. My ID card says its from Ofaten, Morocco and is Middle Devonian in age. Is it correct?

Last, I have some trilobites that I think are from the Wheeler Shale. I think they are Elrathia. Unfortunately, I don't have more information on them. I received them as a gift from my dad when I was around 5. I didn't think to take down notes on location, formation, and age at the time. :P

I believe the first two are flexicalymene ouzreghi.

The next is definitely a gerastos, probably tuberculatus.

The first wheeler shale bug is an elrathia. A closer pic of the second would help, but I think it's also elrathia.

Okay, this one's a little trickier, for the most part it looks like a normal elrathia, except for the genal spines. The spines on this one seem longer and thinner than is typical from the elrathia I've seen. Maybe it's a less common species or some developmental phase :shrug:
