Attribution’s Share is the Plane of Boethiah, The Hunting Grounds is the changing realm of Hircine, Mephala's Realm is called "Mephala's Web", Sanguine has 10,000 realms (I highly doubt they would ever make 10,000 realms), Peryite has "Peryite's Pits", Namira has "The Scuttling Void".
It's UESP, so I dunno how accurate it is, but those seem right.
I've never seen those names anywhere.

Anyway, I find all of the Daedra to be too... obsessed over one thing to want to visit one of their realms. Daedra all require things of Mortals, the Nine don't even ask for love. That's why I like Mundus better. Anyway, they could make some really good horror elements with what they've done with Fallout 3. In fact its expansion packs are like nightmares.
They have some idea in the lore section that each daedra is the embodiment of their sphere, such that everything living represents Meridia, everything that is ancient darkness is Namira, everything that is darkness represents Nocturnal, and all conspiracies to cast curses of pestilence in the evening to destroy hunter's libedo in their sleep are Azura, Boethia, Clavicus Vile, Hermaeus Mora, Hircine, Jyggalag, Malacath, Mehrunes Dagon, Mephala, Meridia, Namira, Nocturnal, Molag Bal, Sanguine, Sheogorath, and Vaermina.
That's why I don't buy that idea. I prefer what Clavicus Vile tells you when you're in his realm in Redguard. He says that the things they do are based on their interests, because they are very powerful beings that are bored. Like this quote of his.
All our time is free time. It's eternity, man. Don't you think that gets a bit tedious? Mostly it's the same thing, over and over, so boring.
Boredom to them is our entertainment, because they're willing to do outlandish things, like screw with elf gods and send packs of werewolves to attack people. If you ask me, it's a much better angle than someone being the embodiment of dawn.
