It can be a square, a trapezium, a quadrilateral or a triangle - depending on the inclination of the plane which defines the cross section.

A cross-section of a cuboid is the two-dimensional shape that results from cutting the cuboid with a plane. It is formed by the intersection of the plane with the three-dimensional cuboid. The cross-section of a cuboid can be a rectangle, square, or even a triangle, depending on how the cuboid is cut. The shape and size of the cross-section will vary based on the orientation and angle of the cutting plane relative to the cuboid.
The formula for cross section area of a square is very easy to use. Measure the length of one side of the square it. If you are doing the cross section area of a rectangle, measure both sides and multiply them together.

You cannot have a 2d pyramid - whether or not it is square based. The 2d cross section will depend on the plane of the cross section.
It depends on the pyramid. If it is a square based pyramid, a horizontal plane will give a square cross section, a plane inclined by a rotation parallel to one of the base axes will give a rectangular cross section whereas a plane inclined by rotation along both basal axes will result in a parallelogram cross section. Not sure how you get a parallelogram from a pentagonal or hexagonal (etc) pyramid.
Yes, a square can be a cross-section of a pyramid, depending on how the cross-section is taken. If the cut is made parallel to the base of the pyramid and at a height where the sides are still straight and converge, the resulting section can be a square. However, this is only possible if the pyramid's base is also a square and the cut is made at the right height.

The following are some shapes having a square cross section: a cube, a cuboid, a square pyramid.

Depending on the inclination of the plane used for the cross-section, it could be a square, rectangle, trapezium, triangle.
The horizontal cross-section of a pyramid forms a square when the pyramid has a square base and is sliced parallel to that base. This is because all points on the cross-section are equidistant from the center of the base, maintaining the same proportions as the base itself. As the cut is made at any height, the resulting shape remains a square, regardless of the height of the slice. If the pyramid's base were a different shape, the cross-section would reflect that shape instead.
square pyramid
When a square pyramid is sliced by a plane parallel to its base, the cross section formed is a smaller square. The size of the square depends on the distance from the apex of the pyramid to the slicing plane; as the plane moves downward, the area of the square decreases proportionally. This maintains the shape's similarity to the base of the pyramid.
A vertical cross section of a square pyramid is obtained by slicing through the pyramid along a plane that passes through its apex and is perpendicular to the base. This cross section typically takes the shape of a triangle, with the base of the triangle corresponding to one side of the pyramid's square base and the apex representing the peak of the pyramid. The height of the triangle reflects the height of the pyramid, while the base length can vary depending on where the cut is made. This representation helps visualize the pyramid's structure in a two-dimensional format.
