In Pokemon Emerald, a PokeNav feature called Match Call was added that allows you to keep track of certain NPC trainers and see whether or not they're available for a rematch. The trainers who are available for rematch at the moment have a tiny Pokeball icon next to their name:
Battling with these trainers will remove the icon from next to their name. It seems like only a finite number can be available for rematch at any given time, so it's necessary to battle some of them in order for others to become available.
I know that trainers who are not or cannot be registered typically cannot be battled again, but it seems like some trainers registered on Match Call, such as Young Couple Kira & Dan in the Abandoned Ship, are never available for a rematch. Others, like Triathlete Abigail on Cycling Road, are sometimes available. Is there anything that can be done to rematch trainers like Kira & Dan? If not, which trainers that are registered on Match Call will never be available for further battle?

If you look up these regions on Bulbapedia, it says they do offer several rematches.
Possible explanation for this (also from Bulbapedia):
The more often the player steps in an area that includes a Trainer that can be rematched, the more likely each Trainer in that area is going to be ready for a rematch.
So if you never go near these areas, your chances of getting rematches from trainers there are slim.
