The two bullets with two rings are Sharp's. I'm not a pro on exactly what Sharp's, but they are most definitely Sharps. The one with three rings seems to be a typical three ring. Now, the bullet on the far right, is that a 69 caliber? If so, nice find... There are some good Civil War bullet identifers on this forum. I dig Civil War battle sites, but I can only tell you so much about each...
Oh...and it looks like you have some nice chew marks on a couple of those bullets. Great Finds!
