Pfff... It's going to be hard to put a value on each photograph.
The site you want to check out is most probably
Bricklink.com: the best online marketplace for buying and selling Lego parts, which has pricing info on every type piece of Lego ever made. Be warned, it is not a very user-friendly site though. The forum there might be another way to have these lots appraised.
The parts you are showing all look to be used, with some yellowing and some scratching, so the total value will not be high. Personally, I'd say the highest single part value is in the
red Lego storage cases, which are currently priced at 6 to 10 EUR.
The chain links in the 10th picture down are also valuable, especially in the reasonably large quantity you seem to own (around 0.10 - 0.20 EUR a piece). Of interest to Lego fans (=value) would also be the printed road signs, and the old style minifigures (no arms, unprinted head).
Also handy to know is that a couple of years ago, Lego changed a couple of colors, specifically gray and brown. The light gray pieces you have are now known as old light gray. Due to those colors not being produced anymore, they are getting rare and actively sought out
(although other people try to avoid using these out-dated colours).
