I think I found a name for them:  
The left is called: jackpot (that name idea was actually already given from a derbibooru user name @spearmint and I have to give the credit to him.)
 
The middle is called: roulette (because it’s the name that I come and it was kind of beautiful…kind of.)
 
The right is called: Spade (because I was about to call her blackjack but unfortunately there is already a blackjack in another OC from Fallout Equestria so I called her Spade instead.)

We need more pictures of these lovely ladies :)

@Otterhand  
prob cause these three had like, 5 total seconds of screentime as minor background figures

odd these three never really hit off.  
not like the way the Bimbettes did…  
 
FIGHT!…or kiss which ever is fine.
