I know from experience that the light brown coloured armatus can be a little bit of a bully to other fish. I kept a 8 inch armatus with my 10 inch jardini and the eel was brave enough to attact the aro. That didn't really work so i put m in another tank because they were constantly fighting eachother. However, this is only with the light armatus, the darker 1 doesnt attack other big fish.
here's a pic of my light armatus when it was a bit smaller

i think you can put all eels together, if sizes kinda match

i have a 14 inch fire eel with a 10 inch tire track for the last 6 months and they get along fine, always hiding out together.
