Well this half dozen are almost finished, still 3 lions and 3 medium types to get finished too.

So from left to right we have:

Laquearius

Retiarius with a spear and rete rather than a trident.

Standard Retiarius 

Sagittarius 

Velite ( or possibly a venator/bestiaries or even a noxii (cannon fodder)

And the last one…. errrrr he is a parmularius as he is carrying a small shield, but after that is anyone’s guess. He isn’t a thraex as he doesn’t carry a sica, or for that matter wear a helmet. If he had a curved blade in his shield hand it could be argued that he is a scissor. As it stands he is a medium gladiator.
