A circle
(There is no shape that exists which has only one side if you are not explicit in your wording. A circle has two sides: there is the outside and the inside. I would suggest reconsidering the phrasing of the question to exclude my answer, otherwise an intelligent person with a penchant for words will have to be given credit for answering none in response to the question as it stands.)
A line. Or a circle
Irregular shape is the term given to an object which has 1 flat side, 1 curved side, no corners but has curved edges.

A shape that has 12 corners is called a dodecagon. This shape not only has 12 corners but alsoÊ12 sides.

A line. Or a circle
I guess you could say that a Mobius strip is a one-sided shape. Or a circle, because there are no corners or divisions where another side starts.
2 side 2 corners and same lenght
The shape with the most corners is a polygon called a "myriagon," which has 10,000 sides and 10,000 corners. In general, the number of corners in a polygon is equal to the number of sides. Therefore, a myriagon has the most corners compared to any other polygon.
A cylinder.
One curved side and NO corners.
A sphere.
A cube is one
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 shape that has 12 corners is called a dodecagon. This shape not only has 12 corners but alsoÊ12 sides.
