Hey,
Can we find Standard deviation of a distribution if we have the mean of the distribution?

Of course not. You'd need the distribution itself, or at least some samples from the distribution.

What if it is a Uniform Distribution or Lognormal distribution?

No, neither of those distributions. It is only possible for a few special 1-parameter distributions like the exponential and the Poisson. (Maybe only those two--I don't know of another.)
