Puzzle #11 - Restore the temple at the ruins (requires Level 3 of Construction). Drag a villager to the ruins in the southeast of the island and they will begin restoring the ruins.

Puzzle #12 - Requires puzzle #11 complete and Level 3 Spirituality. Drag a builder to the shiny rock on the west side of the village and they will chisel the rock to create an idol.

Puzzle #6 - You need to complete puzzle #5 first and have a villager with level 3 harvesting. Take a master farmer to the lagoon and they will start hunting fish. This may take awhile.

Hope this gets you unstuck. If you google the name of the game you will find the strategy guide free by the developer.

Drop a master farmer into the lagoon...it may take a few attempts but they will find a strange fish...the fish of fertlity
