8 is not "Airborne Rifle" as Deogg posts. It is the dark gray version of Rip Cord's rifle from the Tactical Battle PLatform.
2, 4, 10, 18 and 19 Definitely are TF guns. (2 I think is from Stunticons and 4 is from Aerielbots set, 10 is from a Combaticon --Blades, I believe)
6/7 from the Pac Rat Flame Thrower
And yes, Falcone, that is a WOW girl. I do not know her name, but I can confirm that it is. I had almost all of them myself up until last year. She is a Fashion Model (Cover Girl at work?)
