This is q very cool collection, I have some but not on that scale. I will try and ID a few before I go to sleep hopefully.
A few things to check is any markings under the base, be advise without the age they could be made of lead.
From a quick look at the photos you have Napoleon and his battle., as well as what appears some deal in the middle east. and finally looks li!e English going up against the US.
hope this helps for now, I will try and see what else I can find out. we have a few stories with loads of thses. One thing get some good clear shots of the bottom of the base plate on as many different ones as you can.
Sorry I wasn't much Help, been a long day and an really tired.
