The easiest way is to add a trigger volume to each camera, and use OnTriggerEnter to activate the camera and OnTriggerExit to deactivate it: click the camera and add a spherical collider to it (menu Component/Physics/Sphere Collider), then in the Inspector / Sphere Collider set Is Trigger and adjust the Radius to cover the volume you want. Finally, attach this script to the camera:

function Start(){
  camera.enabled = false;
}

function OnTriggerEnter(other: Collider){
  if (other.CompareTag("Player")){ // remember to tag the player as "Player"
    camera.enabled = true; // enable camera
  }
}

function OnTriggerExit(other: Collider){
  if (other.CompareTag("Player")){
    camera.enabled = false; // player out of range - disable camera
  }
}

If there are overlapping regions, more than one extra camera may be active at the same time; you may use each camera’s Depth value to define a “priority”: the camera with higher Depth will be rendered over the others (default Depth = 0).
