Bottle carbonation can usually take anywhere from 2 to 4 weeks. The bottles need to be kept in warm place. If you are desperate to start drinking the beer then test one a week until it is done. A good tip is to bottle at least one plastic PET bottle so you can squeeze test. If they fail to carbonate then you may have leaky caps or used too little priming agent. To test the caps you can fit a balloon over a couple of bottles to see if they inflate. If there is not enough priming agent and they have failed after several weeks, you can open and pour back into a bottling bucket, then bottle again. Once the beer is carbonated you can then move to a cooler storage place. Carbonation requires very little suspended yeast so as long as you've not had a extremely long fermentation or allowed you wort to be heated then there will be enough yeast for carbonation.
