[RC232] In a point to multi point scenario, (host with clients) can the host see the received signal levels of the clients when they transmit data?

Yes, by enabling RSSI append the receiver will measure signal strength and add one RSSI byte as the last byte of the UART message. For details see data sheet page  12
