Points and corners are all vertices!
a trapezuim
A pyramid is constructed from a square base (having four corners) and four triangles, rising from each side of the square with their tips meeting at one point. These five two-dimensional shapes form the faces of the three-dimensional shape of the pyramid, that therefore has five vertices (at the four corners of the square and at the point where the triangles meet).
A cross typically has four corners, one at each end of its two intersecting lines. The center point where the lines cross is not considered a corner. Therefore, the total number of corners in a standard cross is four.

A cube is one

Arizona, Utah, Colorado, and New Mexico all touch at one point, known as the Four Corners.

4 faces 12 corners i think thats right... ;]
There is not a shape with the most corners. You could always "one-up" the last shape. It is like with numbers, there is not a highest number, but instead there is infinity.
A cube is one
A sphere.
Many shapes with three or more corners satisfy the condition. All triangles have 3 corners but not such that they are all equal. One which does is the equilateral triangle. A square and rectangle each have four corners, and by definition also have at least 3 equal corners. A trapezoid and parallelogram each has four corners but have pairs of obtuse and acute angles and so cannot satisfy the condition.
The four states that meet at a single point are Arizona, Colorado, New Mexico, and Utah at the Four Corners Monument.
