A cylinder has a circular cross section that is parallel to its base.
A sphere, a cone, a section of a sphere or ellipsoid, a torus (doughnut) sliced by a plane perpendicular to its axis, a paraboloid. These are some examples.
trapezoidal cross section
Every cross-section of a sphere is a circle.
A cross section of an ellipsoid or sphere. A cone. A [right] truncated paraboloid (like the reflector of a car headlight). There are several others.

Ah, what a delightful little shape we have here! It sounds like you're describing a cylinder, my friend. With its two flat faces, one curved face, and two curved edges, it's a lovely shape to paint happy little trees on. Just remember, there are no mistakes, only happy accidents.
Not a right cross-section.

A paraboloid.
cross-section of a root
Yes a prism can have a square cross-section
No, a cube cannot have an octagonal cross-section.
The cross section can be a triangle, rectangle or a hexagon.
