A triangular pyramid is a pyramid with a triangular base. A tetrahedron is a triangular pyramid with congruent equilateral triangles for each of its faces
For a tetrahedron, the angle between and edge and a face is arctan( square root of 2)
the angle between two faces is 2(arctan(square root 2)) Angle between the segments joining the center and the vertices is arccos (-1/3)
Other triangular pyramids have different angles which will depend on weather it is regular or not, and the details of the sides lengths.
Four.
Yes. Four solid angles comprising 12 plane angles.

If a triangular based pyramid has any right angles it has three. (Think of the corner of a cube). There are many triangular based pyramids that do not have any right angles.
None normally
No but a right angle triangle does
Yes. Four solid angles comprising 12 plane angles.
4*180 = 720 degrees.
