Draenei - can get massive numbers from AU Draenor, Eredar and Krokul from Argus who were helping the Illidari, and Outland. They were slow breeders which makes sense.. they're immortal, no need to hurry to do anything. Children are prized and valued, and they can afford to wait for the right circumstance.. they'd been on draenor thousands of years, but their population wasn't that high - however we don't know if they can speed up reproduction..maybe the light helps them?
For night elves, it is more interesting. But... like OP says, they can "uncurse" the Farondis, get the emerald dream worgen back, and restore some Satyr into Illidari, create a new sub/allied race via the naga - like the Naz'dorei - this gains them populations to the highborne, druids, Illidair, and a new allied race. Plus they can claw some numbers from the ngihtborne if the fruit of the Arcan'dor does fully reverse the nightwell damage returning them to their night elf forms - i have seen suggestions of splitting the nightborne where those born kaldorei revert back to them eventually and are generally more in support of hte kaldorei anyway, while those born Shal'dorei under the dome, don't revert and tend to be more supportive of the blood elves. Elune has some priests we defeated/liberated in the Cathedral/ToS.. if she restores those, that is more numbers.
The NElf groups aren't as big as the draenei, but they can potentially fill up 3 -4 zones.. Farondis are a whole zone, Emerald dream worgen also a whole zone, Satyra and Naga restored could potentially be fairly large too, although if you make hte naga a half naga/NIGHT elf like the naz'dorei concept, that will help for a night elf faction of allies.
