Various iron/lead objects found at civil war site

[bluegrass digger]

If anyone could help identify the objects that I am having trouble identify. Sure, I could speculate, but I know someone in the forum has a better idea. The site has produced a large number of civil war camp relics and hardly any modern trash. I've found a ton of nails as one would at a civil war camp site. Therefore, I feel the objects are civil war related and any help would be much appreciated. I want to add that the two pictures of two objects are iron with a lead back.

Number 7 appears to be a sling swivel from a rifle or musket.

DIGGER 1 AND 4 GO TOGETHER FOR I HAVE THE SAME ITEM AND WAS TOLD A PICK FOR EITHER A POWDER BAG OR CLEANING PICK FOR A CANNON FUSE HOLE MINE HAS A POINTED END, 9- I THINK A TRACE CHAIN PART , 7 SLING . FOR THE ITEMS I MENTIONED A FELLA TOLD MINE WERE ASSOCIATED WITH THE CIVIL WAR.

Number 1 might be part of a friction primer for firing a cannon. The primer is inserted into the cannon vent, a lanyard hooked to it and sharply jerked, which ignites the primer, setting
off the main charge. Here is a picture of a friction primer that hasn't been fired, and you can see the part I'm talking about.

Number eight is a spike, and number nine is a toggle off a chain. The toggle is turned to lay along the chain, then inserted through a ring. Kind of a quick hookup and quick release.

They are used today when rafting logs on a log pond, yours is probably off something to do with a horse or mule pulling something.
And I agree, number 7 is a sling swivel.

Great responses. Often I was hesitant to dig iron signals, thinking it would be another nail. However, I'm glad that I have. In addition to the iron relics above, I've found a bayonet tip, gun tool/wrench, and two bullet extracting worm tools.
