Looks like a 1798 first hair style from what I can see and a 1805 and 07 all with environmental damage did you dig them up or find them metal detecting?
Can't tell from the pic probably an 1801 that someone tried to make a key date 1804 but is impossible to tell from pics I just have an iPhone so it can be hard to tell
Second one is 1805 S-268, third one is 1807 S-276. First one looks like Type II hair Large 8, I'm thinking S-165. And the last one I thinking 1803 S-256.
