Need Help Identifying Type of Bottom Bracket (with pictures)

#1 and #4 are cup & cone, square taper, 3-piece BBs.
#2 is probably a version of cartridge BB
Can't really help with #3. The BMX crowd does things slightly differntly, and with different names. I think I'm seeing a locknut, so I'd guess a similar bearing design as with #1 and #4, although crankarm interface is different.

A standard lockring wrench for the lockring; the cup should work with the Park HCW-11:
