An octagonal based pyramid has 9 faces
A three-dimensional shape with five faces is called a triangular prism. It has two triangular faces and three rectangular faces, connecting the corresponding sides of the triangles. This shape has a total of 5 faces, 9 edges, and 6 vertices.
A triangular prism.
Triangular Prism Triangular Prism 5 faces, 9 edges 6 vertices
The three-dimensional figure that has double the number of edges as faces is a triangular prism. A triangular prism has 5 faces (2 triangular bases and 3 rectangular lateral faces) and 9 edges. Since 9 edges are indeed double the 5 faces, the triangular prism fits the criteria.
A nine sided plane figure is a nonagon. A nine sided three dimensional figure is a nonahedron.

Three of them which are 9, 0 and 9
A 9-sided solid is called a nonagon when referring to its two-dimensional counterpart. In three dimensions, a solid with nine faces can be referred to as a nonagonal prism if it has two nonagonal bases and rectangular faces connecting them. Alternatively, it could be called a nonagonal bipyramid if it consists of two pyramids joined at their bases.
