Are there any free tools for collaborative prototyping interfaces?
There are Ninjamock, he's cool, but it cannot be used for cooperative prototyping. You can show the prototype to friends, but together you can not do.
Whether there are free collaborative tools to create site layouts?
Ninjamock + Google Docs - stuff like that.

Google Docs + draw.io = put the plugin in the Google docks and everything works fine.
