Which one of these are the hardiest?

  All three will be injured by prolonged exposure to freezing temperatures, Papayas especially... ( Can be one of the first " tender " plants to show obvious damage after a heavy frost ).. 

Depending on the variety / cultivar, both Mango and Dragon Fruit can tolerate a little more cold exposure. Grown in warm 9b areas here and in California, same w/ Dragon Fruit.  Goes below ~28F repeatedly each winter?, going to be tough to grow either, regardless of variety.

In Durango, I would try a mango in a sunny protected spot on the south side of a large building or wall that reflects heat and sunshine in the cool winter. It can take occasional cool temps into the 30s, but it needs them to be brief and return to 70s and 80s consistently even in the winter or else they will limp along and be sad. Several days in the 60s are OK if its dry and sunny.

Dragonfruit can grow in the canopy of large trees which can also protect it from cold. I think it's worth a shot. 

Papayas could be grown from seed indoors and planted out in the Spring in order to harvest before any possible cold damage in winter I would think.

Yes, I need to rely heavy on Microclimate and perhaps give it some extra heat using old christmas lights and burlap the plants if there is a bad freeze coming. I will plant them outside my gate on a southfacing wall. Its crazy how different microclimates are within a small area. My bananas once got cold burn so I had to cut them down over half, 200 meters away there was another banana fruiting with zero damage. 
 

its allways dry and sunny in the winter. The cold spells are very brief in the middle of the night, 

People grow edible Dominican Bananas here so I guess there is hope for any of the 3.
