O.K. Posting from rec.crafts.metalworking as usual.
799) This is a strange one. At least part of it appears to be
a plane designed for grooving the edge of a board, with a guide
on one side to keep it on track -- but I'm not at all sure what
the semi-circular bronze guide is for. But it appears to have a
precision adjustment, and maybe a scale for measuring its position.
800) At a first guess, I would say that it is intended to stab into
a wall and hold a candle (in the spring clip), and perhaps to
hold a torch or a kerosene lantern in the ring as well.
I *think* that it is shown upside down so the loop beside the
candle holder could be a hook for holding some accessory.
801) At first, I thought that these were to clamp onto a yardstick
to transfer measurements -- but this would require a 2" wide
yardstick -- a bit too wide for those commonly available.
But they still could clamp to a flat board, and serve as a form
of trammel. Just a guess, however.
802) A wrench for accessing things rather difficult to reach
otherwise. And it looks to me as though the other end could
drive sockets (1/2" drive, I think) in similarly awkward
803) Rather specialized forms of cleavers. Perhaps the hooks are
helpful in butchering an animal?
804) A non-skid clamp to fit a 2x4 perhaps? It looks as though
the non-skid teeth were made from a saw blade -- but it does not
look long enough to be actually *usable* as a saw.
Congratulations -- I had to guess at *all* of these, with no
feel of certainty. This is a new level of difficulty. Only (802) seems
fairly clear to me.

According to the owner it's for the top of the ladder where it meets the
building, but I guess it could have been used on the bottom depending on the
ladder and the terrain. I've email it to a couple of fire museums but none
of them had seen one before, so it was probably not mass produced, at least
not country wide.
799 Plane for grooving in preparation for edge-stripe inlays
(earlier answer called it a stringing plane, which I presume is the
800 Candle lamp (sit on table, hang from hook, or stab into
the log cabin wall)
801: These look a lot like my bicycle chain breaker (for pressing
rivets into/out of a chain); probably it's not that, though- the
concave shape indicates it operates near a curved surface,
and one is right-handed and the other left-handed

Some links and more info have been posted on the answer page:
Any more information on this wrench? i think most of us figured out what it
did. We just did not name it right. Is it something that is currently
available to purchase?
A funny note. (I am always getting in trouble with people because i tend to
read and hear things literally.) When I first read the above answer I went,
" Snake wrench?? I did not know that snakes needed wrenches." I quickly
surmised that this referred to the shape and did not have anything to do
with long, slithering reptiles.
