In 2-D: circles, ellipses, smooth loops or in 3-D spheres, ellipsoids, smoothed blobs have none.
A cone has only one vertex.
Then you have 6 vertices. No problem.
Two triangles.
A polygon may have many more than four sides, a triangle has only three vertices.
Yes, irregular shapes can have vertices. A vertex is defined as a point where two or more edges meet, and irregular shapes, which do not have equal sides or angles, can still possess such points. For example, an irregular polygon, like a pentagon with unequal sides and angles, has five vertices. Thus, regardless of their regularity, irregular shapes can contain vertices.
Yes, plane shapes, or two-dimensional geometric figures, can have vertices. A vertex is a point where two or more edges meet. For example, a triangle has three vertices, while a square has four. However, some shapes, like circles, do not have vertices since they have a continuous curve without distinct corners.

For two dimensional shapes, a vertex (plural vertices) is a point where two sides meet.For 3D shapes, a vertex is a point where three or more faces meet.
In two dimensions, all sorts of triangles. In 3 or more dimensions there is no specific name for shapes with three vertices.

An irregular pentagon can have 5 vertices and two right-angles.
You cannot have such a shape because either the shapes must meet at an edge or the vertices must be joined by an edge.
cube and cuboid
Rectangular prism Cube
A sphere, ellipsoid or toroid are examples of shapes with only one face. You cannot get fewer faces than that!
The angles at the vertices. A square has vertices of 90 degrees. A rhombus has two vertices greater than 90 degrees and two vertices less than 90 degrees.
