For the small pistol it should just be the G-6 (smaller, older model of the G-8 (I think that's a G on the deagle one?))
Third red one: TG2 (If I read you right that's a tazer?)
Really I think you should just be naming them by what they are rather than all the fancy scientifical abbreviations. Like Laser Glock, Laser Deagle, Laser Tazer, Laser SMG, Laser Uzi, Laser Rifle A & B, etc.
