For tools that have common chargers, like the DeWalt 18V stuff, you only have to have a couple chargers handy. Ditto the other tools that share similar packs or chargers. I have a ton of 18/14.4 stuff, but I leave two dual-well chargers "permanently" on the shelf for those. A pair of 12V Bosch chargers, one 18V Bosch charger and a 36V DeWalt charger round out my "charging station." For the few items I have that get intermittent use, I take out the chargers for those when they need a charge, though there is space to leave them out. If I should need to charge more than the number of batteries I have chargers for, I pull the chargers from the kit boxes and gang them up as well. I have extra chargers for the various tools (mostly gotten in battery/charger combo packs). This does well for me since I can grab a tool in it's kit box and take it out on a job knowing there is a charger in the box along with at least two batteries. Set up a shelf to line up the chargers, plug them into a multi-outlet power strip and you'll have a handy charging station. When done with the charging, throw the switch on the power strip to kill the unneeded power to the chargers.
