The fig on the right is from the rangers in bonnets pack. Again slightly smaller but usable. The sculpting is quite reasonable.
The fig on the left is from FI17. Smaller than the other figs and seems to be slightly more basically sculpted.
The other figs in the Native command pack. God knows what the guy on the left is doing.
I should say that the Caliver website was very easy to use. With good comunications from them when the order was placed. The order took less than a week to come and was really well packed. I kicked myself afterwards that I didn't order any of the minifigs figures.
