Russian wire money identification

I know one of them is made during fyodor Alexander but I forgot which one and I forgot the others any help would be appreciated

Yes, the first one is Feodor.

Second one is written Ivan, probably Ivan IV.

Third one, I can't read the name, the middle lines where it should appear are very worn.

And for the fourth coin, you posted only one photo. The reverse photo is missing.

Thank you for your help and I fixed it

I see the 4th coin now, thanks.

But it is the toughest of the lot, only the beginning is easily readable.

Thanks. The ivan denga is weighing in at .31 (initially) grams which of the 3-4 dengas do you think it is?

Three or four?? There are more than 40 varieties only here: https://en.numista.com/catalogue/index.php?r=denga&st=all&cat=y&im1=&im2=&ru=1485&ie=&ca=3&no=&v=&a=&dg=&i=&b=&m=&f=&t=&t2=&w=&mt=&u=&g=

To pinpoint the exact variety among that 40 you'll need a real expert. I'm not on that level.
