NH3(g) + H2O(l) <==> NH4+ (aq) + OH- (aq)

a) According to delta H ( Enthalpy ) , which direction the equation will shift ?

b) According to Entropy , which direction the equation will shift ?

c) Assuming that delta G is positive , then delta S is greater than delta H or vise versa ?

+ energy
NH4+ (aq) + OH- (aq) + energy
When you ask which direction the rxn will shift I think you must say "if T is added" or "if P is increased" or some other variable is changed. Perhaps you are asking which direction is spontaneous?
delta H is - according to the rxn as written.
delta S is - according to the rxn as written

If dG is +, then TdS is more + than dH. I guess that means dS is more negative than dH but it's the TdS TERM that counts.
