It depends on the POV.
In my novels the POV is first person.
That ones harder than most because it almost has to be in dialogue.
In the first novel the character was alone so I had few choices and because I wanted the name pulled out somewhere in the first scene I contrived for the character to mumble their name to theirs self.
I have had them dressing in work clothes and scanning their name embroidered on the tunic.
I think that if you were being heavy handed with interiority(internal monologue)It might easily come up.
eg. I think sometimes I'm a bit too easy. But oh no, my mother would say, my Mary would never be that way.
In the second novel I had two characters in the scene and the non-POV character used the POV characters name.
In third POV and omniscient POV it's a bit simpler.
In the case of your example above you could say.
John's parents, Arthur and Maggie, stood above on the balcony.
If you are doing third POV or Omniscient, you want to get the MC's name out there as soon as possible.
Usually while they are doing something.
eg. John started the day with everything under control; however, the instant he stepped into the chaos of the office he realized his error .
As to the 14 characters.
Do you really need that many in the scene?
How many are already introduced to the reader and how many are new characters.?
How many interact with the MC. (Or POV)
I've had scenes where there were clearly over 100 people present, but I only introduced the ones that were important to the scene and only as the POV character was interacting with them. There might have been a dozen names; however they were all previously introduced.
I would only introduce them in the order of importance in moving that scene forward.
