[opening the can of worms that is trying to make sense of demigod family relations? you're brave, hermione.]
Usually if someone has the same godly parent as you, they're half-siblings, but that's just because the gods tend to have flings with lots of humans. The Greek and Romans haven't usually interacted in a friendly way before, though, so I don't think most people have thought too much about what the children of the same god under a different name are to them.
[maybe once the whole threat of a greek/roman war is over, they can actually address these things. though gods know they don't need to make family matters in this pantheon any more complicated.]
My friend has a sister from the opposite side, but they treat each more like real siblings than most of the demigods of the same parent I've seen, so it's not really a typical example. And Zeus does have a daughter on the Greek side, but we have the same mother too so we're full siblings either way.
