I suspect the first and last are single-lip reamers, but I'd have to
see it.
The second is just a repeat of one of your lathe bits.

That one's got me. The lip looks like a reamer, but single-lip reamers
need a bearing surface opposite the cutting edge, like a gundrill. I can't
figure that one out.
