If they look like a peanut still in the shell, they are queen cells. You will have a new queen shortly and all will be well if she successfully mates and begins laying.
If they look like the ends of bullets, IE: round, raised caps, they are drone cells. If they are the only cells you have, your hive is queenless and a replacement queen or otherwise is needed to save the hive.
If they are only a portion of the cells and you have many normal worker cells, the hive is fine.
