North, south east and west are only really relevant to the planet. You can arbitrarily pick a point of reference in the Galaxy and define a “north” from there, but it doesn’t have any relation to how we use those words on earth.
Down is similarly arbitrary. On earth “down” means towards the center of the earth, following the locally dominant pull of gravity. In microgravity, down is whatever you want it to be because it really only exists in your head as a way to orient yourself and organize your craft, life, etc…
