Hi, although this sunflower is a dwarf variety, it's not particularly small, especially with regard to overall spread and leaf size. With the pot size you've mentioned I would only want to grow one plant per pot. You could grow more than one but I think they would be all squashed and may not grow as large as they would on their own
If you're going to go with one I would plant two seeds per pot, each a few inches from the centre. When they've germinated and grown to 3-4 inches tall leave the strongest one in the pot and prick out the other gently and plant it elsewhere or discard it (I hate discarding any seedling).
You could also underplant the sunflower with some other seedlings or plugs and lop off some of the sunflower's lower leaves as it grows and gets much stronger.
If you want more than one sunflower to a pot I would either get a larger pot, if within your budget, or with the current pot plant a couple of seeds equidistant from the edge and centre of the pot. You can always trim the leaves as they grow if they become too squashed.
Also if you have a garden and have any room I would definitely put some in the ground as they would look wonderful, especially as a group. For this I would sow the seeds direct as I think they do better than when transplanted from pots.Sow them in groups of two seeds Place the two seeds just a few inches apart, and the next two about 12"/30cm apart and so on.
As with the pots, leave the strongest seedling in place and either transplant or discard the 'weaker' one. Protect the seedlings from slugs with slug pellets or you can cover them with cut up water bottles or similar.
