There should be three more homunculi because there were at least three humantransmutions that didnt have a homunculus to go to.
1.In the movie Ed tells the Al from the other side one of his adventures and says that that uranium bomb dude tries to bring back his workers.
2.The Sewing Life Alchemist's kid he tried to bring back a couple of times.
3.In the 2nd video game the main villian messed up alot on his transmutation before he got it right
1. You are correct, there should have been some homunculi but if there were, there were no pieces of the philosopher's stone or red water around so they could not have possibly survived so it does not really matter.
2. He just tries to bring back the daughter's body without thinking about her spirit. Without even considering it, the body is a doll/homunculus. That is what i think about that question anyways.
3. What she said is corect, that does not relate to the story.
