The pipes look like a pretty standard collection of kaywoodies & Dr. Grabows. The pipes with the clover leaf one them, unscrew the stems from the pipes and check out the stingers. 4 hole stingers are older than the newer 3 hole design.
The stands with jars are pretty common. The jar was used to store your tobacco
Any of them would probably be good to start with however you may want to pick up a corn cob pipe from a drug store or pipe shop to start with so you don't accidentally char the rim up too bad when your starting out.
Do a Salt & Alcohol treatment on them

and use an alcohol dipped pipes clean down through the stem until they run clean.
