Nice figures. There's some very good value in them, especially the Last 17 figures, of which you have quite a few.
The best thing to do would be to match them up with their weapons and get some closer pics. If you're not sure which ones match, take another pic of the weapons on a piece of white paper. Label them numerically, then do the same with the figs (alphabetically).
This would them make it really simple for us to help you sort them out properly and get s clear value.
Looks like you have between 700-800GBP or so there - if you can find any of the black weapons for either the Luke Poncho, Lando General or A-Wing Pilot then you'll add a minimum of another 50 per weapon
