#5 is, I think, "Road/Kill" miniatures from the 2017 kickstarter.
The long metal parts in #2 may also be from that range and it's possible some of the small gun turrets and things are too.
Three things at top left of #3 looks like the comms tower from that range and something else and a pop-up turret.
The car at the back of #10 is possibly one of the add-on minis.
All currently OOP I think after Mega Minis disappeared.
