2-3 Liters
The average human stomach can hold around 1.5 to 3 liters of gastric fluid, which consists mainly of hydrochloric acid (HCl). The concentration of HCl in the stomach can range from 0.5 to 1.5% by weight.
Hydrochloric acid in the stomach helps to break down food during digestion by activating enzymes and creating an acidic environment that is conducive to digestion. It also helps to kill bacteria and other pathogens that may be present in the food we consume.
4 liters
The gastric mucosa secretes about 2 to 3 liters of gastric juice per day. This acidic fluid aids in the digestion process by breaking down food components. It contains enzymes, hydrochloric acid, mucus, and intrinsic factor.

The stomach's capacity is about 1 qt (0.94 liters) in an adult. Sorry though idk about a kid's
The amount of gastric juice normally secreted per meal is about 700 ml and about 1-3 liters per day. The juice is not made entirely of HCL, as gastric juice contains several other ingredients including water, electrolytes, digestive enzymes and some mucus.
