Goodluck! Some of your babies will take ages to hatch. They will externally pip and some will sit for 24 hours before proceeding, so don't be stressed if they seem to be taking awhile. If it gets to 36 hours after they have externally pipped and they haven't got any further you may have to help out. It's up to you whether you do or not, but 99% of the time the babies turn out absolutely fine. Once they do hatch the sound of their peeping often hurries the others to hatch so don't take them out of the incubator too quick. Don't worry if they are knocking the other eggs around a bit - they will all be fine.
At first, in your brooder, sprinkle ground up food everywhere so that wherever they pick at they will find food. Some of mine aren't even fully dry before they are looking for food. Make sure you have something on the base of your brooder that gives them some grip. Slippery floors will lead to splayed legs (but they are easy and quick to fix if that does happen). After a day or so the babies work out where the food bowl is and after that you can put bedding down. Don't forget they need a shallow dish or chick waterer with marbles in it for a few days too. You may have to show them the water by tapping the surface with your finger to get them interested. They generally copy each other but try to keep an eye on them to make sure everyone knows where the water is.
Baby quail are so adorable!
