In general, any 10-sided polyhedron is called a decahedron. With 10 regular triangles for faces, you may have a pentagonal bipyramid.
Square Based PyramidTetrahedron: A tetrahedron is a polyhedron made of 4 triangles. A "regular tetrahedron" is a tetrahedron where the triangles are equilateral. (A polyhedron is any 3 dimentional figure made of flat surfaces and straight lines.)

The tetrahedron. If one of the four triangles is equilateral and all others are isosceles, then one might also call it a (triangular-based) pyramid.
Its a platonic solid :)
A pentagonal pyramid.
As far as I am aware, there is no polyhedron (3-d figure) whose faces are all octagons. As far as I am aware, there is no polyhedron (3-d figure) whose faces are all octagons.

triangular pyramid
a cube, or a six sider, or a die, much like the ones used in yahtzee!
I would call it a 25-hedron because I want to communicate rather than obfuscate.If I wanted to obfuscate or be pretentious I would call it an icosipentahedron.
You can call it a hexahedron. A hexahedron is any polyhedron with 6 faces. A special kind of hexahedron having 6 faces made of congruent squares is called a cube.
Yes: it's called a tetrahedron. If you're an algebraic topologist, you can also call it a 3-simplex.
