Sphere, ellipsoid, torus, paraboloid, hyperboloid are shapes with only curved surfaces.
Hemisphere, quadrant, cone and cylinder are examples of shapes with curved and plane surfaces.
There are, of course, many others.
Each face of a polyhedron must be a polygon: a flat surface bounded by straight lines. So, if any of the faces is curved, the shape is not a polyhedron.

A hexagon...
Pyramids have some triangular faces.
This shape has 2 opposite identical faces and some other which are parallelograms is a prism. A cylinder shape has 2 circular faces and one curved face.

no, there are only two faces and one is curved therefore cannot be parallel in order for the cone to eventually come to a point, there cannot be any perpendicular faces

they are: ---sided pyramids and triangular prisms and 20 sided 3d shapes
Some visible objects in the sky could be faces and shapes.
It depends on your imagination. Some people 'see' nothing - others see all kinds of weird shapes - including faces.
Many shapes have curves. Some curved shapes include:circle (2-dimensional)cone (3-dimensional)sphere (3-dimensional)cylinder (3-dimensional)
According to the strictest definition of "face" being a flat surface, a cone has one. This leaves no name for the other part of the cone which is a curved surface. Some people call this a face as well.
