Designating the first world colonised in a system with more than one habitable world 'Prime' is yes good and very STAR TREK.
But rather than sticking with Latin (secundus, etc.). If there is only one habitable world I go with its designated number, e.g. Eridani II or Rigel IV.
Where it's the only habitable 'world' and the satellite of a planet I generally name it colony and by the star, for example Altair colony.
Wonder what others do.
