We were holding short of XXL on Sierra and another aircraft; was holding (arriving earlier).  Somewhat unexpectedly; we were cleared for takeoff.  I pushed the Attend button; and slowly crept toward the runway to keep the operational flow going.  After a long delay; and now approaching the runway; I pushed the Attend button again; with no immediate response.  I continued onto the runway. A FA then called us to state they were enforcing a passenger failure to wear a mask issue (this was also an issue during boarding). I directed the FO to ask Tower for a 30 second delay on runway; which was granted. The FA then communicated to me (the exact words I do not recall); that the situation was corrected.  I was fully under the impression that they were ready for departure.  We then executed the takeoff; but as it turns out; a forward FA was still standing in the isle of the cabin and had to take a seat in the aft galley. Once at level-off; we discussed the situation. This was certainly a miscommunication. In addition; they had yet to provide (me) the 'Cleared for Departure' PA.
As the A FA; I was conducting my final walkthrough. I was at the last row of seats. A child that was seated in the last row with her sister and mother was not wearing her mask. The mask was in the mothers bag. This issue had been addressed earlier upon boarding. The CA dinged us for departure.  I called the CA from the AFT galley to let him know the same family was not in mask compliance. I asked if I could call him back and he replied with we are on the runway. Finally got the child in compliance so I asked the D FA to call the CA to let him know the mask was on. 2 rows in front of the mask compliance issue was an elderly lady whom refused to stow her large bag on the floor nor in an overhead bin. I had a bin open to try and coax her into letting me stow the bag for her when we took off so I took the nearest jumpseat for takeoff.
Air carrier Captain and a Flight Attendant reported a Flight Attendant was still standing during takeoff roll due having to deal with a passenger not complying with face mask policy.
