How to hook four strain gauges ( 5 wire) to esp32
These loadcells already have a wheatstone bridge in it, you only need to wire it up correctly. According to the homepage the wiring is as follows:
Red:power + 
Black:power -
Green:signal +
White: signal - 
Maybe the 5th wire isn't used or not important for you.

The exication voltage shouldn't be a problem. Just put the supply voltage of the HX711 to power+ and power-. The signal+ goes to in+ and signal- to in- of your HX711 module.
According to its datasheet the HX711 has a serial protocol so you can wire it up ti the SDIO interface of your ESP32.
This datasheet has an example C-driver in it.
