Have you used the i2c scan lua script to see if they are being detected at the address you have set

ArduPilot/ardupilot/blob/master/libraries/AP_Scripting/examples/i2c_scan.lua

-- This script scans for devices on the i2c bus
local address = 0
local found = 0

local i2c_bus = i2c:get_device(0,0)
i2c_bus:set_retries(10)

function update() -- this is the loop which periodically runs

  i2c_bus:set_address(address)

  if i2c_bus:read_registers(0) then
      gcs:send_text(0, "Found I2C at " .. tostring(address))
      found = found + 1
  end

  address = address + 1
  if address == 127 then
    address = 0
    gcs:send_text(0, "Found " .. tostring(found) .. " devices")

To use rangefinders for proximity you need to set PRX1_TYPE = 4 that will tell it to use rangefinders as proximity sensors and it will show up on the proximity display.

It still sounds like you have not programmed the new address to the range finders correctly if all you get is rangerfinder 1, if you plug another rangefinder in and it also shows as rangefinder1 then it has the same address and has not been programmed correct.
