Cone....

There is not a specific name.
There is no specific name. There cannot be a shape with one straight side. And , if it is not straight, there are many many options available: a circle or ellipse being two of the better "behaved" shapes. A squiggly curve would do as well.
There can be no such shape. If there were a shape with n flat surfaces, then if you sliced off one vertex, you would have a shape with n+1 flat surfaces. So it is always possible to add one more flat surface.
