Button id
 

Hope it's OK to ask about more than one button...
But here goes ......not sure if these are the correct letters that I've given you .
1 LF - ?
2. EG ?
3.?
4.DY?
5.FV? Frampton volunteers?
6.?

Most were discovered metal detecting years ago (although not by myself)

Thanks for any information you may give .

I think the first two are livery buttons.
4 - Devon / Dorset...Yeomanry Cavalry?
5 - Fencible Volunteers?

Thank you for your help and suggestions . just a pity the buttons have gone to far in the way of condition.

I think 4 has three letters with the middle being V probably something volunteer infantry. Its just not aligned right to have the 'Y' directly under the crown.
