Police say at least two men opened fire at around 03:00 local time (07:00 GMT) as 1,000 people were enjoying the local art, music and food.
One of the suspects, a 33-year-old man, was shot dead and another is in custody, a local prosecutor said.
Four of the injured, including the teenager, are in a critical condition.
Police initially put the injured toll at 20 but raised it after two more victims arrived at local hospitals.
The motive for the attack is not yet clear. Several weapons were said to have been found at the scene.
