The locations of the gangs in Calexico listed above go as followed:

Caleixco

-> Central gang: Tijuana Cartel

-> Western San Diego, California, USA: Blue Waves, Dungeon Collectors

-> Eastern San Diego, California, USA: Heroicdoers, Darksiders

-> Tijuana, Baja California, Mexico: Demons of Revenge, Las Calcitas Grande

Not just that, but GTA: Aldrich's Biggest Scorch will feature gang allegiance trifectas, as you will see on each of their agenda tabs to see which local gang from a different section of the same map they are in as well as which international gang they are closely associated with.

Behind the work

-> The idea for inventing the gang of surfers Blue Waves is mostly inspired by the racing faction Wave Rippers in Hot Wheels: Highway 35 World Race, who also have the same blue accents and similar vehicles like Alec "Hud" Wood's Switchback but the Blue Waves themselves drive mostly sports cars and trucks. Their leader Steve Sherwood looks a bit like Super Macho Man from Punch-Out!! Wii and he often talks in surfer lingo and never even swears.

-> The Dungeon Collectors are largely inspired by the Nerds clique from the 2006 videogame Bully, which Rockstar Games also published, along with several other works of fiction that featured the nerd subculture, like The Simpsons which the gang's name is loosely based on The Android's Dungeon & Baseball Card Shop and one of the Treehouse of Horror's villains The Collector, whose real-life alter-ego is Comic Book Guy, whom the Dungeon Collectors' leader is hugely based on.

-> Because the Darksiders are a gang of disgraceful, angry gamers, they are entirely based on countless infamous Let's Players. Their leader, Will Freeburn, is entirely based on Phil Burnell, A.K.A. DarksydePhil or THE KING OF HATE, whose pet peeves are constantly blaming everything he does wrong in games he plays on the games themselves or their developers / publishers, being rude to everyone including his fans, having extremely low intelligence and shorter attention span.

-> Las Grandes Calcitas are a Salvadorean marabunta gang based in Tijuana, as to the Marabunta Grande being based in Los Angeles in Grand Theft Auto V. Their gang name is roughly Spanish for "The Big Calcites".
