If the electric field E = 0 at a point, the electric potential V may be zero, or may not be zero.
The relation between E and V (in one dimension) is, E = -dV/dx.
So, if E = 0, dV/dx = 0; For sure, it only means that the space rate of change of V is 0. Or V remains constant as x changes. Or we may say the potential V is constant or uniform in space. For this to be true V = 0 is a special case. That is V could be zero but not necessarily zero. V can have any positive or negative constant value as well.

Not necessarily .Electric intensity may be zero even if electrostatic potential is constant .Electric intensity is E=-dV/dr,where 'dV' is the change in potential over a small distance 'dr' .If V is constant then V does not change that is dV is zero and E=0.

No.
electrostatic potential is the work done in bringing an unit positive charge from inf. to that point. So potential at a point will not be necessarily zero if intensity, i.e. electric force is zero at that point.
You can also see this from the fact that a constant potential gives zero field too.

Both r uncorrelated coz electrostatic potential does not depend upon electrostatic Intensity.
Rather electrostatic Intensity and change (or difference or gradient) of electrostatic potential are correlated.

intensity is the change in the potential
i.e.
I = d(V)/dt
so if we have a constant value of petential then it is true that intensity will be 0
also 0 value of potential is possible only at infinity(assumed)
so intensity at infinity will be 0 as well

Yes, electric pottential at a point is 0 if electric field intensity at that point is 0.
