If the moving body is rigid, then E denotes kinetic energy, where E = (mv^2)/2 and v approaches c (velocity of light).

In general, E in Einstein's mass-energy equivalence denotes the fire energy and light energy of a moving object. If the object is rigid, then E is the kinetic energy, where E = (mv)/2.

Einstein's mass-energy equivalence is just one value for the velocity in kinetic energy equation. Am i right?

E = (mv^2)/2 is the kinetic energy equation. Here, sqrt(2) * c = 423970560 m/s, where c = 299792458 m/s is speed of the light in vacuum. E = (m*[sqrt(2) * c]^2)/2 = mc^2. ER=m*(423970560 m/s)^2,...

In the Universe, all the objects (except running in vacuum) are orbiting other object(s)or moving in a circular path. Why?

I think these phenomena follow the scientific facts defined in the classical mechanics, but not theories or definitions in Einstein's mechanics.
