First, I think you are rushing the process. If the bees made a queen cell on the 9th, (and that is highly unlikely, it normally takes a day or two or more for them to know they are queenless and make the cells) then the queen cells would emerge after the 26th. If the queen cells were started on the 11th or 12th, you could expect emerging queens on or about the 28th or 29th.
If the queen cells are still capped, and not emerged, the bees will tend them until they are sure they are not going to emerge. If a queen has emerged and left the hive for mating, the bees will not normally tear down the other queen cells until she returns, and, starts laying. And it is possible that the eggs that they used in the queen cells are not all the same age. Could vary by one or two days. With multiple queen cells, it is not uncommon to have more than one queen in the hive for several days.
It is late for starting the process of letting the bees make their own queen. I would give it a few more days, (5 to 7) then, it there is no queen laying, I would introduce a new queen.
Newly hatched bees will be accepted almost anywhere, almost any time. You can normally move frames of newly hatched bees without much fear of not being accepted. a That being said, not sure how many newly emerged bees will be leaving the parent colony until they need cleansing flights or rest. As they age they will leave your trap and then depending on how you are trapping they may or may not be able to get back into the parent colony.
If I had 6.5 frames of bees, I would move them now, and start the process over. If you do not want two colonies you can combine them later using the newspaper method, or a double screen. You could add some to any weak hive using the same methods. Reason I would move them is, If they are queenless they can become quite mean, and at 6.5 full frames they will be getting crowded very soon. By moving the 6.5 you will have a new box to work with, more room for the bees, and you are weakening the colony.
You didn't provide if you are trapping for elimination, or making starts, and, you didn't state if you are using a screen cone funnel and external hive body or a trap with/without funnel inside the hive body and sealed/not sealed to the feral source. For readers to give good advice they need this info. I would think more will chime in with advice, if they had more information, in order to help you.
