@elad-applepar For question #1, if you are talking about adding a second GPS for redundancy then it is possible depending on which GPS unit you choose and which configuration option you choose for the Starling 2 Max. The GPS unit would have to be UART based, not CAN or SPI based. And you would need to choose the WiFi configuration of the Starling 2 Max because that has an add on board that exposes a UART connection. Then you would need to enable a driver for the second GPS in PX4. This isn't something we have tried but it is theoretically possible to do. I would only undertake this if you are comfortable modifying drones and dealing with px4 configurations.
