Post a picture of your setup, provide details on the LCD.
The CO2 sensor indeed claims to have a 3.3V level UART, so that should be fine.
Where did you connect BME280 to?
My experience with pulling too much current from the Pi's 3.3V rail is that it will no longer boot until the components get removed. I've never managed to 'burn' a Zero ...
How do you power that setup?
