Short answer: no.
Inferno R1 and Inferno Alliance are released, you can get them at the INF website, (click the icon on a team member, the orange I). These are unmaintained (as the Inferno team is currently working on INFR1U and INFASA respectively, which are SCP-compatible upgrades to these), so if they don't work in the latest build, too bad. Just wait a few years. They aren't too good either (INFR1 is ok).
Inferno R2 doesn't exist. It's the official sequel to Inferno R1, but it doesn't exist, because no one ever made it. Doesn't exist. It's a figment of your imagination. Just like FreeSpace 6.
Sol: A History is a fanmade prequel. Check the second page of the Inferno board, there is an upgrade so it runs on a semi-recent version of FSO. If it doesn't work anymore, too bad, no one's fixing it (unless you bug ShadowGorrath enough).
Solar Wars is a fanmade sequel. I've never played it but apparently its terrible. You don't want to play it, apparently.
Inferno SCP is not released yet.
