Hi Viperskin!
Congratulations you found 6! Queens!
Camponotus herculeanus likes it dry, but give access to water, like you already explained. They don't need food at the beginning, but you can try and serve them some fruit flies or little insects. As my queen arrived she took some honeywater, too. Just mix some honey with a bit of water and serve it on a small plate.
The best thing would be, if you get some test tubes and prepare them for the Ants. A little bit water into the tube, perhabs 3-4cm, then a piece of cotton down to the water, very close to the surface, so that the cotton gets a little bit wet. Don't push it into the water.
Put the tubes into the boxes make them dark and the queens will move into there.
Good Luck...
