1. double bump rake - raking, scrubbing pins
2. snow man (double ball) - picking wafer locks
3. short diamond - picking individual (more advanced technique with this pick) or raking
4. [looks like] broken key extractor - take out broken key bits or pick bits
5. snake (rake) - raking, scrubbing pins
6. hook/feeler pick - individual picking of pins
that was just at a glance, I'm not sure if I got all the specifics down, but it'll give you an idea
