The Range display shows range measurements. Each one is a cone starting at the origin of the frame given in the header of the sensor_msgs/Range message and fanning out in the +X direction of that frame.
To display multiple ranges (like from a robot with several sonars), publish a TF frame at each sonar location. Publish the range messages with the corresponding frame_id in each header. Then in rviz, in the Range display properties, set "Buffer Length" to the number of range sensors on your robot.
