I'm not very fond of the names, but I'm not sure which are serious proposals and which are just temporary.
I don't think we should copy the -versalis everywhere, so I'd not call our star Solarversalis. I'm fine with having some inner lava rocky planets, that seems interesting. I wouldn't call a planet Vulcan, it was already the name of a hypothetical planet in our solar system. I'd also avoid Juptur and possibly Septuhn because they seem similar to Jupiter and Saturn, and Octane because it's the name of a molecule and I just don't really think it's a good name for a planet.
I'm not really coming up with new ideas for the solar system because I'm not really interested in designing it all atm, but I don't really know when I would so I guess I'll just comment on your proposals sometimes.
A question though is if we'll have common names for planets, or if every language will have their own words for the planets, in which case I'm not sure it makes sense to speak of official planet names. If -versalis gets dropped in everywhere and I end up disagreeing a lot with the names I might just give them Blaxian names for Blaist Blaland. The planet names I came up with for my original solar system in 2009 before Universalis:
Star: Pola
Kronaxo: Lava world
Ziva: Earth-like with life (but not civilizations)
Noxium: Earth-like, comparable to universalis
Uxnua: Gas giant similar to Uranus
Klanaxon: Red gas giant similar to Jupiter, 4 times as massive and with thin rings
Ixnaix: Gas giant similar to Neptune
