You are only limited on the number of packs you can charge at once by the board you use, which I see connectors for four packs.
You should be able to charge up to four of any cell count from 2s to 6s simultaneously.
The math comes in to play when you try to figure what max charge rate you can set for a given number of packs, and cell count, the limiting factors being the max wattage from the power supply, max charger charge rate, and lipo battery c rating.
