H retusa 'White Ghost'
H fasciata (zebra plant)
and finally a tiny one, its in a 3 inch pot, to give you and idea of how little!
closeup
I have several more! I love these plants! 
I'd say the first one maybe right, after looking about the web, it seems there are glabrata forms very much like that one, I called it H. Tortuosa in my head when I saw it.
The limafolia is right, there several firms of it too!
Long thin leaves, short stout leaves, striated etc...your is kinna middle of the road.
The cooperi could be right too, it's splayed open look threw me off, but after lookin at your pic better, your prolly right, I'd give it more light, if you have more that is.
Grey ghost is most often listed as retusa, it's not, many authorities say it's turgida, while other say it's accuminata, I'm with them!
The zebra plant pic is confusing, the littler garner ones in from may be fasciata, the tall ones almost certainly attenuata.
Attenuata has tubercles on the top, or inside if the leaf, fasciata does not.
I also see that truncata hiding in that pic! I gotta get one!
What's the dark green one to the right in that pic? It looks like your glabrata but I think I see white spots too.
That last little guy is anyone's guess!
Mirabilis hybrid sounds good, reminds me of bristle king.
H. Herbacae also comes to mind, but who knows!
I'll take pics if a few more if mine today
