My village has been saying "worried about house". I have three hut build. Where else can I built. The ruin has been fix. I am on the stone right now.

If your villagers have built 3 huts (puzzles 1, 3, and 6), there are no more huts to build. The best way to stop your villagers from being worried about housing after they have built all of the huts is to train them on another skill, such as Medicine or Farming.
