I believe Firion can use several types of weapons, but only his own, AKA he has with him a lance a bow an axe etc, but he can't use someone elses weapon like a gunblade for example. I'ts cool how his main sword is the bloodsword as it was the most effective weapon oddly enough against the emperor.
Lamont- actually their name may be a mispronunciation, such as their name for Gilgamesh which is still pronounced and spelled something on the lines of Girugameshu. I'm not saying that the english versions don't mistranslate anything, but when the remakes came and had everything supposedly translated better, names like that stayed the same while others were changed, i think Firion is based on another mediteranean name anyway.
Also, for a movie as awsome as this, i feel no shame for my statement earlier
