Yes, although a triangle (in normal geometry) can only have one right angle, no more. It is possible for a triangle to have all three right angles in spherical geometry (if you were to draw the triangle on a sphere).

yes
All three interior angles of a spherical triangle may be right angles.
Presuming our geometry is Euclidean, such a shape would be a rectangle, since all 4 angles would be right angles. If our geometry is hyperbolic, it would be possible to construct such a quadrilateral which is not a rectangle (and in fact, rectangles cannot exist in a hyperbolic geometry). I do not believe such a quadrilateral has any special name.
they don't. most likely in the level of math you're taking, it is assumed that all cones are right cones
polyhedrons need flat face and edges, corners which cylinder cones don't have.

There are four right angles in a square or rectangular geometry
A right triangle in geometry is a triangle that has 90 degrees as one of its angles.
Geometry is all about measurement.
review the topics from the last year geometry regents topics at jmap.org and all u have to do is get 25 questions right and u get a 72

In geometry, magnitude is the length of the hypotenuse of a right triangle.
yes
Euclid, a Greek mathematician, is credited with creating the theory of solving right angles. His work is known as Euclidean geometry, which laid the foundation for modern geometry.
