Dilute sulfuric acid H2SO4 is an indifferent acid to oxidising substances, while HCl (potential +1.36V) is a reductant and HNO3 (potential +0.96V) is an oxidant.
Hydrochloric acid being a very good reducing agent, will interfere with the titrations and be oxidised to chlorine by potassium permanganate. Hence sulfuric acid is used, and not HCl.
The usual primary standard for acid-base titration is sulfuric acid. Nitric acid tends to lose NO2 by volatilization and HCl is also more volatile.
Sulphuric Acid (H2SO4) is used in the redox titration process because it provides the H(+) ions necessary for the reaction to occur more quickly whilst the sulphate(-) ions barely react during the reaction.
Sulfuric acid is usually kept in glass containers.
Sulfuric acid is an acid that is used in the science of Chemistry. Sulfuric acid can be purchased from companies such as "Science Company" but is also available for purchase from Amazon.

KMnO4 will oxidize the HCl to Cl2 gas, a potentially hazardous vapor.

Yes sulfuric acid is used in manufacturing of plastics, rubber and fertilizers.
Because sulphuric acid is non volatile and its sulphate ion is not interfering during the titration process while HCl is a volatile substance and its chloride ion interfere in the reaction as a reducing agent.
The fluorescence of quinine is stronger in sulfuric acid solutions.
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.
