the first one i don't think came from a set, i just want to know how much he could be worth.  Photo 2, I can't find the chestplate anywhere! The robot arm on the third photo probably didn't come with that model. The cape in the third photo has some kind of creature's head in the little gold circle. The 5th picture i just want to know whether it is worth anything on it's own. Thanks!

Picture 1 is basic Town body parts put together.

Picture 2 looks like this part to me: http://alpha.bricklink.com/pages/clone/catalogitem.page?P=2587pb30#T=C&C=65

Picture 3 is a mish mash of different figures. Head was in Indiana Jones I think, body is a Geonosian from Star Wars, and metal arm is from Agents

Picture 4 I do not believe to be Lego

Picture 5 is shield from Roman Soldier http://alpha.bricklink.com/pages/clone/catalogitem.page?S=col06-10#T=S&O={"ii":1}
