while only time varying electric field can create the magnetic field then how the steady electric field in a conductor can produce magnetic field around it?

Your mixing two problems. The static magnetic field is not generated by the electrical field in the conductor rather than the electrical current (respectively the moving charge carriers).
 

while a time varying electric field ====>time varying magnetic field
time varying magnetic field =====>time varying electric field

steady electric current ====>steady magnetic field

the third phenomenon is different from two of them above?

No, the magnetostatic field can be considered as a special case of the general general electromagnetic field properties. It's the same with the electrostatic field.

Both static fields can only exist in the presence of matter while EM waves also exist in empty space. But you can't maintain a static current or charge distribution without physical charge carriers.
