When all the first 5 are dry, I would scoop them out and leave the last two a bit longer.
For the egg that has not pipped, you can candle that and see if it has internally pipped, lightly tapping on the big end should encourage a response. The egg that has externally pipped requires the high humidity, so a warm sponge put in when you get the dry chicks out will help get the humidity back up.
I don't normally encourage opening up when there is an external pip but you be able to help it, or, it may have already died. How long has it been still?
Sometimes, it's just not meant to be, and only the strong make it out.
