nopes. radian is the ratio between the length of an arc and its radius. A steradian can be defined as the solid angle subtended at the center of a unit sphere by a unit area on its surface. For a general sphere of radius r, any portion of its surface with area A = r2 subtends one steradian.

None. A radian is a measure of angular separation in 1-dimensional space, a steradian is a measure in 2-dimensional space. It makes no sense to try to convert from one to the other.

None. A degree is a measure of angular separation in 1-dimensional space, a steradian is a measure in 2-dimensional space. It makes no sense to try to convert from one to the other.

There are 2*pi stradians or tau steradians in a hemisphere.

None. A degree is a measure of angular separation in 1-dimensional space, a steradian is a measure in 2-dimensional space. It makes no sense to try to convert from one to the other.

Radiant intensity is a radiometric quantity, measured in watts per steradian (W/sr).

SI unit of plane angle is radians (rad) and that of solid angle is steradian (sr)

Supplementary units are two in numbers. They are radian for plane angle and steradian for solid angle.

Cannot be converted as the dimensions of the units do not match. You can however convert candlepower to lumen/steradian.
