Should these herbs be planted in bunches or no?

I bought some potted herbs yesterday and they have a few plants in a single pot. Should I only put one plant in the ground or should I just use one? I also have rosemary cuttings... Should I plant these together or only plant one? The plants I got in pots are marjoram, oregano, thyme, lavender, basil, and dill. The dill, basil, and lavender I know for sure have more than one plant in them. Not sure about the others, they just look like small bushes.
