no not all pyramids are polyhedron because each pyramid has a different shape. so no each pyramid is not a polyhedron

Yes they are.
No. Polyhedrons are any shape with multiple sides. A triangle and a prism are just two different kinds of polyhedrons.
they are not sometimes prisms
Not true.
True. Some polyhedrons do not fit the definitions of prisms or pyramids. For example, a truncated tetrahedron is a polyhedron that has faces that are not all parallel and does not converge to a single point, which disqualifies it from being categorized as a prism or a pyramid.
Not all polyhedrons are prisms or pyramids. A polyhedron is defined as a three-dimensional shape with flat polygonal faces, straight edges, and vertices. While prisms have two parallel faces (bases) connected by rectangular lateral faces, and pyramids have a base and triangular faces that converge at a point, there are other types of polyhedrons, such as irregular polyhedra, that do not fit these definitions. Examples include shapes like the truncated tetrahedron or the dodecahedron, which do not qualify as either prisms or pyramids.

Polyhedrons such as pyramids and cuboids
Not all polyhedrons are prisms or pyramids. A polyhedron is defined as a three-dimensional shape with flat polygonal faces, straight edges, and vertices. While prisms have two parallel faces (bases) connected by rectangular lateral faces, and pyramids have a base and triangular faces that converge at a point, there are other types of polyhedrons, such as irregular polyhedra, that do not fit these definitions. Examples include shapes like the truncated tetrahedron or the dodecahedron, which do not qualify as either prisms or pyramids.
Yes, pyramids are considered polyhedrons because they are three-dimensional geometric shapes with flat polygonal faces. A pyramid has a polygonal base and triangular faces that converge at a single point called the apex. The number of triangular faces corresponds to the number of sides on the base polygon, making pyramids a specific type of polyhedron.
Both pyramids and prisms are three dimensional. Both of them have polygon faces. Another thing common about pyramids and prisms is that they have a base and faces.
