Is it possible to send/recieve data from multiple esp32 on one app?

How would i make it possible, if i want to send and recieve data from app to esp and from esp to app? (by bluetooth?)

Bluetooth only work between 2 devices(maybe 3 on special occasions). But, you can connect the ESP32 modules with each other over WiFi, making one master and multiple slaves, and you can send and receive data from them though the master over BT.
