Nice finds! The point is a classic "Eastern" style made from kettle scrap by either a trader or Native. I say eastern because of the triangular shape with a hole.
99 out of a 100 points made from copper kettle metal out here in the west are typically like this.....
The Jesuit ring dates from around 1650 to 1750 and is always a great find in my books.
I'd say those were more likely used as fishing weights as they would be a little heavy to hang as pendants (although they did hang large cowbells from their garb later on) if they're close to 2 inches in length.
I do have the exact holed triangular lead objects like yours found out here in the west at fur trade sites only.
Thanks for sharing.
In the Collectors's Illustrated Encyclopedia of the American Revolution (pg 270) By Neuman and Kravic they are listed as trade pendants. My only reference...
