No 3 is often too many for a pig that young. She couldn't feed the last 2 properly so they didn't grow right compared to the 3rd one That then probably caused issues with giving birth and the last one ended up not making it either. They also could all still be premature from her being too small and young to carry that many full term. I doubt there's anything you could have done especially with 2 of them not being fully formed. Even with special care all the premature babies we've tried to save would go into seizures and die a week or 2 later.
