2 - star wars tripod leg
5 - a-team harness?
6 - star wars endor ranger gun
7 - star wars millennium falcon seat
8 - star wars ISP-6 gun
10 - same as 2
11 - star wars endor ranger front gun
13 - star wars rebel transport escape hatch
14 - action force backpack, figure unknown??
15 - star wars tie fighter seat (vader or inceptor)
16 - star wars ISP-6 windshield
17 - star wars snowspeeder engine
18 - star wars millennium falcon ramp strut

#2 looks like a leg from a Tri-pod Laser Canon
#7 looks like the main chair piece from the Millenium Falcon
#8 looks like a canon from an ISP-6 mini rig
#10 another leg from a Tri-pod Laser Canon
#15 I don't have mine handy at the moment but it might be the cockpit seat from a Snow Speeder
#16 I don't have mine handy at the moment but it might be the cockpit canopy from a Snow Speeder
#17 looks like the rear exhaust piece from a Snow Speeder
#18 ramp strut from the Millenium Falcon

That's all I can help with at the moments.

Edit: looks like Stefan beat me to a few of them.

Great thanks for the replies, more Star Wars stuff than I thought

#3 is the laser pistol from the Castle Grayskull play set(He Man and The Masters of the Universe) .

They sell for around $20 on ebay
