Is it possible to change the UART2 for the UART1 in pin A9 and A10 in the example of ping pong in the STM32 cube expansion LRWAN?

Yes

Can you tell me what files I must change to have the communication?:grinning_face_with_sweat:

You don't mention a board, but typically the builds have an xyz_hw_conf.h type file, and that addresses 95% of things that need definitions changed. Might need to chase down an interrupt handler and GPIO_AF​ setting, or double check them.
