What do you mean?
So there are a few different answers depending on device?
For example, iPhone 4 and below can be put on any iOS that you have device specific blobs for. (Same for ipad1/2?)
I think you can bring the iPhone 5 to iOS 6 with Odysseus.
Anything after the 5 though, specifically the phones with 64bit architectures, you cannot install any old versions, or unsigned, iOS

That will not.
I skipped iOS 6 so I never paid that much attention to it, but what I've assimilated through other jailbreak research/obsession is that you can downgrade to iOS 6 only through some kind of special magic that the final OTA iOS 6 allows.
But that would be where it ends. Blobs became irrelevant because Apple changed the method of checking whether an iOS can be installed.
So it's the latest iOS 6 jailbreak, or what you have now.
THEORETICALLY there is an iOS 9.2 and 9.3 jailbreak being released within a month / 2 months, but at this point it's a single guy talking, who hasn't been disproven yet? take it with a grain of salt, I am assuming it is BS for now and will be pleasantly surprised if this dude turns out to be legit.

TL/DR I'm not sure, but I think not. Maybe a new jailbreak soon.
Well I heard the iPhone 7 is virtually unjailbreakble which is disspoining
