    Based on extensive air shower simulations it is shown that the electron distributions with respect to the two angles, determining electron direction at a given shower age, for a fixed electron energy and lateral distance, are universal. It means that the distributions do not depend on the primary particle energy or mass (thus, neither on the interaction model), shower zenith angle or shower to shower fluctuations, if they are taken at the same shower age. Together with previous work showing the universality of the distributions of the electron energy, of the lateral distance (integrated over angles) and of the angle (integrated over lateral distance) for fixed electron energy this paper completes a full universal description of the electron states at various shower ages. Analytical parametrizations of the full electron states are given. It is also shown that some distributions can be described by a smaller than five numbers of variables, the new ones being products of the old ones raised to some powers.\
    The accuracy of the present parametrization is sufficiently good for applying to showers with the primary energy uncertainty of 14$\%$ (as it is at the Pierre Auger Observatory). The shower fluctuations in the chosen
