cone
The intersection of two or more solids can either be an empty set, a point (two cones "intersecting" apex-to-apex), a line (two cubes touching along one edge), a face (two cubes, face-to-face). If the solids are "filled", the overlapping intersection will be another solid. If they are hollow, it will be a closed three dimensional figure.
A sphere intersected by two parallel planes equidistant from its centre, An ellipsoid intersected by two parallel planes equidistant from its centre, A uniform hyperboloid intersected by two parallel planes equidistant from its centre, A torus with a wedge removed, A cylinder.
If it is two parallel side, rather than two pairs, then it could be a right angled trapezoid, a rectangle or a square.
The two parallel and congruent faces of a solid are called bases. In three-dimensional geometry, these bases can serve as the top and bottom faces of shapes like prisms and cylinders. The congruence and parallelism of the bases are key characteristics that define these solids.
A non-regular quadrilateral can have either zero, one, or two pairs of parallel sides. If it has no parallel sides, it is called a trapezoid; if it has one pair of parallel sides, it is still considered a trapezoid; and if it has two pairs of parallel sides, it is classified as a parallelogram. Thus, the maximum number of parallel sides a non-regular quadrilateral can have is two.

A sphere, ellipsoid or toroid are examples of shapes with only one face. You cannot get fewer faces than that!
The circles could be in 2 planes that are parallel to each other. Lines and planes can be parallel. Lines of latitude are examples of circles that are in parallel planes.
Two rays could come from adjacent sources. If they are both in the same direction, they would be parallel to each other. Or one ray could be bonced off two mirrors like a letter Z to create two parallel rays.
If it is two parallel side, rather than two pairs, then it could be a right angled trapezoid, a rectangle or a square.
Not necessarily. They could be skew lines, and satisfy these conditions.
The two types of solids are amorphous and crystalline solid!

They could be if they are both skew to the same line.
