I'm afraid I don't have a very scientific approach to these so am not sure of exact numbers. I don't transplant the parsley and coriander but just sow them quite thinly. I've had parsley in my garden container all this winter because it's been so mild and basil and parsley on the kitchen windowsill (the basil looks quite sorry for itself though because I let the room get too cold when we went away last weekend).
I harvest fairly sparingly and let the plants regrow.
I don't use any fertiliser on any of them.
I think the problem with supermarket pots is that they plant loads of seeds in each pot so that they look great when you buy them but then start over-competing with each other very quickly.
