Cadian, Catachan, No idea about the rest.
Cadian Chestpiece / Legs
Catachan Head? and backpack I think?
The gun I am not sure about I really don't collect guard, it looks like something from Necomunder? or whatever it is. The sword is off a assassin, Eversaw if I am correct. Not sure on spelling. Binoculars command squad.
No idea about the rest, can't see the backpack etc really well.
