Does anyone know what type of boats these are?

These are indeed Butterfly sailboats made by the Barnett. They are very popular in the upper-midwest and are nice little scows. I have sailed them in Michigan and Wisconsin.

If they are in decent shape that sounds like a great deal on the boats. Hopefully, you would get more parts than what is shown in the picture. Did you buy them?
