They are all going to have sedement in the bottom of them, from bottle conditioning. One question, How did you mix the priming sugar in? or did you use carb tabs? If you primed the whole batch then leaving the beer sit in the demijohn will kick off fermentation again and you will have to re-prime the last gallon, not a big deal.
Oh yeah...............Get a bottling bucket!
