Yes it can. Imagine a square with the corner cut off. The remaining shape is a pentagon with three right angles.
Strictly speaking a pentagon is a plane figure with five straight sides and five angles, so yes, a pentagon can have one - or more - right angles. Imagine a rectangle with one of the corners cut off - that would have five sides and three right angles. .......... ............. ................ .................. .................. .................. ..................
It's primarily a template for drawing lines at accurate right-angles and other angles to a line, usually 30º / 60º and 45º for standard set-squares. It's also used for drawing parallel lines. Adjustable set-squares allow you to set off other angles.

With two mirrors at right angles you will have 3 (360/90 - 1) images of an object. Two of these are primary and the third is secondary. Some light rays from the object bounce of each of the mirrors to your eye to form the two primary images. But there are other rays that bounce off a mirror onto the second mirror before they get to you. This produced the secondary image.
Right angles are used in architecture. All buildings are essentially based off of right angles (from the ground to a wall).

It depends on the degree of rounding. To the nearest 90 (eg for angles measured in degrees to right angles), 134.99....

They can, if you start off with a square, and make a diagonal line from a little out on the top line to the bottom right-hand corner.

Any non-regular polygon from pentagon and up can have two or more right angles. Take a square and chop off the top and then make a two more connecting line segments (like a house with roof), and you have an irregular pentagon with 2 right angles at the bottom, for example.
Light reflects off a flat mirror because the surface is smooth and polished, causing light rays to bounce off at equal angles of incidence and reflection. This results in the image of an object being reflected as if it were on the other side of the mirror.

I'm going based off the movies were he is seen laying on his side with now gone ear facing up. He is laying on his right side down implying that he lost his left ear.
That is correct. A square, by definition, has four right angles. (I remember back at junior school for being told off for creating an 'irregular square' because the angles weren't accurate!) I think (somebody may correct me) that in a rhombus, each set of two corners must match with their angles, anything else is a quadrilateral.
