Looks a lot like the Young Triangle Cactus ( Acanthocereus tetragonus ) i have..  Younger stems look a bit different than when more mature, possessing more and much smaller/ denser spines. Another possibility is one of the Harissia sp. but 4 angled stems speak " Acanthocereus" imo.

This said.. There is supposedly another, quite obscure ( and rare ) atm, sp. of Acanthocereus that has been recorded from Coastal Thorn Scrub areas of Northern Sinaloa / far Southern Sonora. Have only been able to find a picture or two online, and not 100% convinced they're the real deal since A. tetrogonus has been planted almost everywhere and apparently look similar.

I have another NOID Cacti that shares similar spine arrangement as yours in the 2nd pic but has 5 angles on the stem, and spirals as it elongates a bit.

At this point, regardless of the species, Some pics of what the mother Triangle out front looks like / flowers. Spectacular when in full bloom, Fruit is supposedly edible and quite sweet ( no fruit produced on mine however ).

Looks like the a. tetragonus cv fairy castle resembles my 2nd pic while a. tetragonus species could easily be the first 

Thanks
