If we're going to be going "um, ACK-SHUALLY" over names here...
Lucifer, Vesper, Hesperos, Phosphoros, Eosphoros, "The Morning Star" and "The Evening Star"—these are all names for the exact same celestial body: the planet Venus.

And as mentioned above, technically speaking, Venat's name is a localized derivative of her Japanese name, which itself is romanized to "Venus". And finally, Venus is the Roman equivalent to the goddess Aphrodite.
If any of this has any meaning on the story as shown, it'll be news to me. I can't access the raid until I hit 565, and that's gonna take a while for me since I get bored with dungeon grinding pretty easily.
