It varies greatly
Theoretically if you wanted to sleep while tied to a dock, and only used the boat for day sailing so there was little gear and provisions aboard, you could sleep six adults and three small children inside, plus two adults outside in the cockpit in good weather. Two adults in forward v berth, two adults in dinette drop down table berth, two adults, one child under the cockpit in the rear. One child on galley seat, one child on galley floor. However, the maximum rated load for the boat is six adults for stability purposes. If you try for maixmum people on board, be sure to have ballast tank fully loaded.Given that we provision, modified and arranged our boat for extended cruising, with 24 gallons of pressure water, Raritan head and 12 gallon holding tank, electric fridge, etc. We only have room for four addlts and two children, which is the current family situation. Two adults in v berth, two adults in dinette drop down berth and two kids in the double bed sized remaining space under the cockpit at the rear. The kids share that space with: spare anchor and rode, waste holding tank, six cheap and four SOLAS approved life vests, bed linens, clothing, 4 fenders, spare rope and other parts, and the electric fridge under the companionway step.If going to sea for coastal cruising, or sleeping while sailing the galley seat is not suitable for a child's sleeping unless a lee board or cloth were instlled to prevent roll off.For just the wife and myself, the usual crew, we sleep in the V berth, to avoid dropping the dining table, and because when anchored or sailing I find it much easier to pop my head out the hatch to visually check weather conditions, or for anchor drag in the middle of the night without disturbing my sleeping partner. Hope this helps.
