Ph scale.
acidity or alkalinity is a measure of the relative amount of H+ and OH- ions dissolved in a solution

a measure of acidity or bacisity.
Gastric juice consists of hydrochloric acid, a strong acid along with many weak acids. Free acidity is a measure of acidity of hydrochloric acid alone but total acidity is a measure of combined acidity due to hydrochloric acid and many weak acids (organic acids and proteins).

pH is a measure of acidity...
The Hammett acidity function (H0) is a measure of acidity that is used for very concentrated solutions of strong acids, including superacids. It was proposed by the physical organic chemist Louis Plack Hammett and is the best-known acidity function used to extend the measure of acidity beyond the dilute aqueous solutions for which the pH scale is useful.
Yes, free H+ concentration is the only measure of acidity.
