A cylinder, a doughnut with a slice cut out by radial planes, a sphere with two slices removed (possibly in a wedge shape), a cone with its top and bottom cut off by horizontal planes, a paraboloid with top and bottom cut off by horizontal planes.
An hemisphere is half of a globe with a circular flat base, a round edge, a curved surface but no vertices.

Euler's definition do not apply to curved solids. faces must be polygons; they cannot be circles. using the conventional definitions of faces, edges and vertices, This question causes frustration for teachers and students. Euler's definitions of edges, faces and vertices only apply to polyhedra. Faces must be polygons, meaning comprised of all straight sides, edges must be straight, and vertices must arise from the meeting of straight edges. As such, a cylinder has no faces, no edges and no vertices, using the definitions as they apply to polyhedra. You need to create a different set of definitions and understandings to apply to solids with curved surfaces.
Faces: 2 circular, 1 curved rectangular. Vertices (not vertexes!): None Edges: 2 circular.

A tube is a type of cylinder, which has two circular faces, one at each end. It also has three edges - two circular edges around the faces and one curved edge around the side. A tube has no vertices, as vertices are defined as the points where edges meet, and a tube's edges do not meet at any points.
Oh, dude, a circular prism? That's like a fancy way of saying a cylinder with a polygonal base. So, it has two faces - the circular ones at the top and bottom, and then all those curved edges around the sides. And don't forget about the vertices, which are basically the corners where the edges meet. So, yeah, it's got 0 vertices because there are no corners on a curve, but hey, who's counting?

None, they have vertices.
