If you really need the metal box, use an external antenna connected via cable to your BLE module. BTDT.

If the box is really "ideal" Faraday cage then nothing will help you. If it isn't then you need to test what are real properties of the system and maybe you will find that it works OK (if you have good BLE module and antenna, throttle Tx Power to max and place radio module to ideal position inside the box. If not then you will see what is actual range and if you need to place some repeater and where (it might be 10m in one direction and 30cm in another). These things can be simulated in specialized SW but then you need very accurate inputs, running experiment is sometimes faster and definitely cheaper.

In case i have multiple sensors can i make a mesh network and push the data to the a common signal amplifier (maybe some kind of repeater)which can maybe push the over all signal to the receiver?

Like make a hole to the metal box which will allow you to do some kind of directional radiation pattern (also depends on antenna tuning on your actual BLE device inside the box) so it might reach certain distance in that direction? If you need to have your box "hermetic" then you pare pretty much out of luck;)
