There's a couple that've been mentioned, though they're not a huge focus of AoS so far despite their cool potention.
The First Smithy, Grugni's personal workshop, is a subrealm that connects to many others and helps let him slip around wherever he pleases. Skagrott's Fungal Asylum is a subrealm accessible through chamon that he's turned his personal lair and prison complex, while a recent kragnos novel also has an offhand mention of a "Pelagic Hinterland" that sits between Ulgu and Chamon, with the aquatic subrealm's entire ocean transforming into slime as an omen of kragnos' return, for some reason.
There are a lot actually
First the Eightpoints is techniacly such a realm.
Then the dwarfs were able to make new realms under Grugnis tutorlige if I recall correctly. And he still has his first smithy, his favorite workshop. .
There is Skagrotts Fungal Asylum where he keeps all his prisoners/fungal calculators to predict the movement of the bad moon
There is the orb inferna above Aqshy. Basicly a planet unto itself, fought over by daemons and allmost conquerd by Khul.
The pelagic realm is an ocean-themed realm (finally!) which was apperently ruined during the era of the beast by turning it into sludge (Buh!)
And many, many more.
Indeed major realms could be considered to be made up of minor realms. Like Chamon, which consits of minir realms floating around, or Shyish with its many and unique afterlives.
Ok so if for my Lizardman homebrew army I cook up that they've moored their temple ship in a demi-realm between Ghur and Ghyran which they use for capturing, breeding and conserving the great beasts of the mortal realms... that is perfectly plausible?
(Apologies for still calling them Lizardmen, I'm stubborn like that.)
I would say this is perfectly plausible. After all the space lizards have world changing engines and are known to have entire jungle systems within their space ships. I believe they could make a new realm if they wanted.
And Ghur and Ghyran are very close (both are realms of life with crazy plants and animals. Its mostly an attitude difference in between them). I would say they are even more twim realms than Ulgu and Hysh . So there being a demi-realm should be a thing.
(I am the one who wrote dwarf in his text... I understand your stubborness. Especially when the new names are a but dumb/silly. Like Orruk spelled the same like Uruk, another term for Orcs from Tolkien. Or gargants instead of giants. Like gargantuan, another term for very huge. You know like giant....)
(I mean, it's all just GW wanting to be able to copy-right things, as is their good right. But as long as it's not confusing people, I'd rather speak "plain-warhammer". Also I think Seraphon is a dumb name for them when everything about them is fantasy mesoamerican... but their name isn't.)
If your lizardmen have a Slann it’s entierly possible they even made that Demi-realm themselves, too. At least on Kroak’s temple-ship, the Draconith were reared and allowed free reign of a small section of Ghur that the Slann, or just kroak personally, had time-space folded over itself, sectioning it off from the wider realm even though it was technically still in the realm sphere itself (like folding a piece of paper over so someone walking across its surface wouldn’t find the bit that’s been folded over, even if it’s still under there).
No reason they couldn’t do the same between two realms, or even build their own in the void between realms, anchored to the laylines that run between them
The Skaven's capital of Blight City occupies a demi-plane from which they burrow to the other realms in order to spread their devious schemes and designs.
It’s its own realm called the Realm of Ruin, which makes sense since the main spell lore of the Skaven is called the Lore of Ruin. Although I’m not sure if you can call it a Mortal Realm or a Realm of Chaos.
As many have said, pocket Realms or sub-realms are fairly frequent.
Allarielle's Glade is one
Shadespire is one
Godeater's Son had one that was a reflection of a mountain in Aqshy
They seem to come up frequently and don't have a lot of rules governing consistency. So go crazy and design something however you want.
It is highly hinted that the realm of nurgle is actually one of these realms, being a combination of Ghur and Ghyran. Said that the bones of many of the beast from both realms were located there
That to me seems unlikely. Nurgle's demesne existed long before the mortal realms and is just part of the realm of Chaos. You could boot up TWWH3 right now and go there in the realm of chaos campaign and that game's take on the setting specifically is fully canon and supported by GW.
That said... I wouldn't be surprised if parts of realms that got thoroughly corrupted enough were literally torn from their realmspheres and absorbed into the demesne of a chaos god within the realm of chaos. So that Nurgle literally has just fused stolen chunks of both realms into his own.
I imagine Tzeentch has done the same with Chamon and Hysh, Khorne with Shyish and Aqshy and Slaanesh would have done the same with Ulghu if he wasn't currently... uhm... occupied.

There is an unnamed one in Prince Maesa’s story.

Shadespire is in Uhl-Gysh. I think the area in God-eaters son was directly beneath Aqshy.
