Circle is the odd-one-out - all the other shapes are 3-dimensional, while a circle is a 2-dimensional figure.
A circle is by definition 2-dimensional (flat). If you mean a circle that is wider in one direction than the other, than you are thinking of an ellipse.
A semicircle is a two-dimensional (2D) shape. It is a closed curve that divides a circle into two equal parts, with one straight edge and one curved edge. In contrast, three-dimensional (3D) shapes have depth, width, and height, such as cubes, spheres, and pyramids.

A circle is a 2-dimensional plane figure composed of a line segment on which every point is the same distancefrom a single point that is not on the line segment. As such, a circle has area but no mass.

No. A circle is 2-dimensional. A sphere, however, is a 3-dimensional object with circular cross-sections.
For it to be three dimensional, it would be a sphere.
I know one of them is a circle
Hm...I'd need to know if you're speaking in terms of algebraic functions (like the difference between a "linear" function and a "quadratic" function), or trying to apply 2-dimensional definitions of "line" to 3-dimensional geometry (like...the equator on the globe is a line [also known as a "great circle"], but it doesn't follow the definition of a 2 dimensional line.

A circle or annulus. Each of its infinite number of diameters is an axis of symmetry. Plus there is the line through its centre and perpendicular to the plane of the circle.
Any two lines or line segments that meet, will form a two dimensional angle. It measures the amount of rotation that is needed to get from one line to the other line.

The cross section of a circle is a circle. A circle is defined as a plane figure (i.e. 2 dimensional object) with a constant radius in both dimensions. Since a cross section is, by definition 2 dimensional, a circle's cross section is the circle itself.
