The docs mention 4 serial UARTs are available
| Port 0: | USB |
| Port 1: | GPS |
| Port 2: | ADC |
| Port 3: | Xbee/telemetry |
My question is in a flying configuration, with telemetry and GPS, is there anything free?
For example: does feeding an OSD by serial mean telemetry or GPS must be given up?

A serial port can be shared. For instance, our next OSD will share Port 3 with the Xbee (but that means that it has to have an onboard MAVLink parser, to interpret the same data stream). But there are no unusued serial ports. BTW, Port 2 is used for the datalogging, not the ADC.
