it's a trapezoid
It has no particular name but it looks like a house.
As many sides as you like providing that it has 3 or more equal sides and equal interior angles
A plane figure with at least three straight sides and angles, and typically five or more.
In Euclidean geometry, a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
A square
a house
a pentagon with two adjacent right angles
A right angle triangle or an obtuse triangle
it's a trapezoid
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.

Oh, dude, you're really reaching for those angles, huh? Yeah, technically, there is a polygon with an interior angle sum of 9000. It's called a nonagon, or a nine-sided polygon. But like, who even needs that many angles, am I right?
As many sides as you like providing that it has 3 or more equal sides and equal interior angles
A regular polygon like an equilateral triangle.
A polygon has exactly as many sides as it has angles.
A polygon is a shape in which every site is a line segment. It can have any number of sides and any number of angles, but always has the same number of sides as it has angles..
