You may or may not have enough bees in there to make a "decent" queen. If however you do end up with a laying queen you may need to supplement them with a frame or 2 of emerging brood to boost their numbers once the queen starts laying. Make sure you have PLENTY of honey and pollen in there and might want to consider a feeder. Next time if you're only going to take a few frames worth of bees put the old queen in with them. Leave the big hive to build queen cells. Or even easier find a local beek you can buy some queen cells from. Colonies low in numbers just don't have what it takes to make the best queens possible. Let this split ride just be aware the resulting queen might have a fairly high likelihood of being superceded at a young age. Best of luck though and the only way you're going to get good at this stuff is by diving in and doing it mistakes and all. Stick with it and the bees will reward you in the end.
