What is the meaning of the -# displayed after the various call signs the cursor shows?

In the AX.25 packet radio protocol the dash and number appended to the callsign is the SSID (Secondary Station Identfier). It is a number from 0-15 that allows up to 16 stations to share the same callsign. -0 is the base callsign and is not displayed.
