Help Identifying Artifacts

[BobGuy]

Hey guys! My cousin asked if I could post some pics of his finds here in Illinois to see if I could get some help identifying them. The points should be fairly easy to research but if anyone sees a familiar point please let me know. The other photo is where we have questions. I know the middle piece is a celt but in not certain in the others. The one to the right if the Celt we found in a creek near a mound and chert quarry and don't have any idea what is. Any help is appreciated!

Thanks!

Cant enlarge the 2nd pic to get a closer look. Guess left to right. Broken Celt, Celt, Triangular knife, Hammer Stone and small Hammer Stone.

Your welcome, I wish I could help you on the points but I just dont know the different types. Hard enough to figure mine out when I find some which has been a while lately. You found some nice looking ones. Somebody here should be able to help I would think.
