I'd say delete all of them except one and just play, maining that one whatever that is. It doesn't have to be the all being class/race, having tons of characters really just distracts from following through. I put in roughly 70 hours on one character doing just act 1.
But I knew exactly what I wanted which was a blonde freckled halfling lady Lore Bard multi-classed Rogue. Also, you can always tweak your class later on.
This is imo, have fun.
