It depends on what kind of prism you mean. For example, a rectangular prism has 6 bases and a triangular prism has 5 bases. A triangular prism only has two bases.
Every prism has a base. For a triangular prism the base is a triangle.
A triangular prism has five bases because it can be flipped over to form five different bases
It has two bases, as is the case with all prisms.

It could be called a pentahedral prism.
A triangle.
It depends on what kind of prism you mean. For example, a rectangular prism has 6 bases and a triangular prism has 5 bases. A triangular prism only has two bases.
It depends on the prism. A prism that has a regular pentagon as base but is not a right prism has no right angles. At the other extreme, consider a right prism whose bases are pentagons that resemble a child's drawing of a house (square with a triangle roof). If the angles of the roof triangle are 90-45-45, the prism will have 22 right angles.
A heptagonal prism has two 7-sided bases.
There are 9 sides on a triangular prism.

None. By definition, a triangular prism has triangular bases. If it had circular bases it would be a circular prism (cylinder).
Every prism has a base. For a triangular prism the base is a triangle.
It depends on the prism but cones will always have one.
