The ammonium ion (NH4+) is mildly acidic.
It is not to be confused with ammonia (NH3), which is basic
NH4+ ions are weakly acidic (pKa=9.23) and NO3- is neutral. So pH is about 5 for dilute solutions.

Ammonium sulfate is slightly acidic. When dissolved in water, it forms ammonium ions (NH4+) and sulfate ions (SO4^2-), which can slightly increase the acidity of the solution.
The conjugate acid of any substance is given by removing an acidic hydrogen. In the case of ammonium ion, the conjugate base is ammonia.
The pH of NH4+ (ammonium ion) depends on the concentration of NH4+ and the pH of the solution it is in. When ammonia (NH3) reacts with water to form NH4+, the pH of the solution decreases, making it slightly acidic. At low concentrations, NH4+ will have a pH close to 7 (neutral), but at higher concentrations, it can decrease to slightly below 7.

The HCl is hydrochloric acid

Ammonia (NH3) is a weak base. It can accept a proton (H+) to form the ammonium ion (NH4+), making the solution basic.

Ammonium hydroxide (NH4OH) is a base. The cation (NH4)+ is low acidic.
NH4Cl, an ammonium salt is chemically neutral, as it is formed by the neutralization reaction of an acid and a base.
In general, cations of Group 1 and Group 2 elements, transition metals, and NH4+ are acidic in nature. Anions of strong acids (Cl-, Br-, I-, NO3-, ClO4-, ClO3-, ClO2-) are basic. Anions of weak acids (e.g., CH3COO-, HCO3-, H2PO4-) are generally acidic.
NH4 +One plus.
Usually ammonia is basic. It cant be neutral or acidic.
