Normally four but there could be six if the opposite edges at the apex met at right angles.
A square, by definition, must have four right angles. A plane shape with 4 right angles which is not a square is a rectangle.
A rhombus looks like a lopsided square, or a diamond shape. It is a parallelogram with four equal sides. The angles of a rhombus do not all need to be equal BUT opposite angles of a rhombus ARE equal. If you were to "straighten it up" and make all the angles equal at right angles, it would be a square. A rhombus with four right angles is a square.
Rectangle and square

No angles are larger than 90 degrees in a square based pyramid.
Yes - it has four around the base !

There are no right angles in a square based pyramid, so Pythagoras and his theorem are not involved.
Yes its base contains 4 corner right angles
Just the one and it is the base face
No, but a square pyramid does.
Square-based pyramid.
A square pyramid has a total of 8 angles. Each of the 4 triangular faces has 3 angles, totaling 12 angles. However, 4 of these angles are shared where the faces meet at the base, resulting in a total of 8 unique angles in a square pyramid.

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.
