Oops! The varieties are as follows.

Musa Dwarf Orinoco banana tree
Musa Dwarf Cavendish Banana tree
Musa Dwarf Red Banana tree
Musa Double Mahoi Banana tree
Musa Dwarf Namwa Banana tree

Has anyone had success with these indoors?

Dwarf cavendish... Yes
Someone sent me two pups last summer and they've very well inside. Just haven't gotten any taller than two feet. I'm assuming they aren't going to get too tall because I'm starting to see pups budding at the base of each.
Plus I like the mottled leaves.

I find Bananas.org wiki to be a helpful source of info: http://www.bananas.org/w/index.php?title=Special:Allpages

Dwarf doesn't always mean "dwarf".
Both my Dwarf Namwah and Dwarf Jamaican Red are taller than my Raja Puri and my Grand Nain. My RP (fruiting) is 5 foot to the top of the P-stem, my GN (flowering) is 6 foot to the top of the P-stem. My DJR (not flowering yet) is at 8 foot to the top of the P-stem and my DN (not flowering yet) is at 9 foot to the top of the P-stem.
Add another couple feet to each to get to the tips if the leaves.
