a circle
Many shapes can have right angles, including rectangles, squares, and right triangles. Additionally, some polygons, like trapezoids and certain types of irregular shapes, can also contain right angles. The key characteristic of a right angle is that it measures 90 degrees, so any shape with at least one angle that meets this criterion can be considered to have a right angle. There is no specific limit to the number of shapes that can possess right angles, as they can be found in both regular and irregular forms.
Here's a list of shapes that need a right angle: square rectangle right triangle
It's not that easy to answer because a straight angle is like a straight line and I think that it would be on either every or none of the shapes that I would know of. Any shape has a right, obtuse,or acute angle. So, I am guessing that no shapes have straight angles. or that a straight angle is in every angle which is not true.

rectangles
There is no standard angle for a battlefield (not battlefeild!) since they come in all shapes.

There are many such shapes. A circle is perhaps the most obvious.
There are many possible shapes with two acute angles.
