I’m inclined to think not. If there were multiple cities and schools on one planet the kids would be familiar with the idea that they are all built to identical plans and just think “oh we are in another city”. Nine planets, nine identical cities, no other habitation.Despite the Star Wars tendency towards single biosphere planets it's still worth reminding that we saw just one metropolitan area, and a single school. There could be sentients or droids, elsewhere, performing activities like farming and mining. The former would almost certainly be happening if the planet is truly isolated, and self sufficient.
