Why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves?

Are the nodes of ranvier found at a regular interval only on myelinated peripheral nerve fibers?

No, the nodes of Ranvier are found at regular intervals on both myelinated central and peripheral nerve fibers. They are gaps in the myelin sheath where the axon is exposed, allowing for the propagation of action potentials along the nerve fiber.
