I'm currently at 20 cultivars here in Kansas, probably 50-80 p-stems if I count only solitary plants and pups over 3'.
Little Prince
Truly Tiny
SDC
DC
Double* [suspicious that it might be a Dwarf Namwah]
Grand Nain
Williams Hybrid
Highgate
Cocos
Gros Michel
Dwarf Red
Dwarf Orinoco
California Gold
Dwarf Brazilian
Dwarf Namwah
Fake Ice Cream (a tallish Namwah)
Kluay Kai/Glui Kai (or some such spelling)
Raja Puri
Pisang Ceylon
SH-3640
DC, Williams Hybrid, and Double* are currently fruiting. Most of the others will probably start producing fruit next year.
