Yes, all of the radii in a single circle are congruent.
A part of a circle enclosed by two radii is called a sector.
I always called it an arc. It is simply a section of the circle. The ends are determined by the two radii you referenced. Each of the radii start at the center of the circle and end at their intersection with the circle. The portion of the circle that lies between the ends of the two radii is an arc.
The plural of 'radius' is 'radii', not 'radiuses'. A circle has an infinite number of radii, but they are all of the same length.

Circular Ring Sector.
No. A sector is bounded by part two radii and part of the circumference.
A sector of a circle would fit the given description

A sector.
The area bounded by an arc of circle and two radii is known as a "circular sector"

the good part.
Working in degrees, the angle of the greater radius, minus the lesser radius, all over 360, gives the proportion of the area of the circle that is bounded by the radii. This can then be multiplied by the area of the whole circle to give the bounded area.
a sector is a portion of a circle bounded by the two radii and the included arc.
