I know you're having doubts now, but you really did the best thing by bringing them all indoors. I've been doing TNR with feral colonies for a few years. The kittens that I'm able to catch or coax indoors all do fine. The ones that I can't get to almost all die. Even if they survive outside they just get trapped in the cycle of hunger-fear-disease-danger that other feral cats are in.
You've given them the best chance possible by taking them in. Just hang in there.
That's great news about getting them to pee and drink a little formula.
