im going to assume that you'll be bass fishing due to your needing a flipping stick and needing 4 rods that will cover most of the applications you'll be fishing well. go shorter if from shoredue to some casting issues with trees, branches etc, longer if from boat. powers and actions are variable due to your preference in feel and fishing style. for a graphite cranking rod, id lean more towards moderate, but a glass one id go for fast.
id go with:
6'3"-7'2" medium power fast action spinning rod from 1/8-1/2 for finesse stuff like shakeyheads, finesse jigs, dropshot, trigged worms, senkos, tubes etc.
6'6"-7'0" medium-medium heavy power moderate to fast action casting rod from 1/4-3/4 for spinnerbaits, buzzbaits, chatterbaits, and crankbaits. a nice glass stick would work here.
7'0"-7'11" telescopic flipping/pitching stick for heavier jigs, topwater frogs, slop stuff, punching jigs.
6'6"-7'0" medium-medium heavy power fast-ex fast action casting rod 1/4-3/4 for trigged, senkos, lighter jigs, swim jigs, creature baits, casting spoons, and topwater sammys and poppers. also can double as a buzzbait/spinnerbait stick.
