Can anyone help me identify these tools and what they're used for?

#1 Hole transfer punch - lets you mark a skin hole location given a hidden hole on a part (eg. a rib) under the skin.

#2 Dunno...:)

#3 Cleans alum stuff that is clogging your files

#4 If it's got a 14/28 tapped hole in the top it's an extension for threaded drill bits - if it's around 1/2 diameter it may be the bit you hit in a C-frame dimpler in which case it would have a 3/16 smooth hole at the top end.

#1 is refered to by two different names.
Hole finder or strap duplicator.
It doesn't punch matching holes...
It has a hardened steel drill guide that is used to match drill a hole in a new sheet of aluminum that is laying over (and covering) a hole underneath.

#4 is an alternate arbor that comes with the Avery C-frame tool.
The end is machined to fit in a rivet gun.
Very useful for back riveting with a C-frame tool (riveting wing spars is one use) but very few people seem to have ever been taught how.

#2 is a staple /cut nail puller. Place the open jaws around the fastener you want to remove, hot with a hammer to drive the jaws into the surrounding material, and then pry up against the foot of the tool. This will close the jaws around the offending nail and allow it to be removed from the parent material.

#3 is a file card. It is used as a brush against a file to dislodge and remove imbedded material from the groves of a file.
