Three schemes of neutrino mixings (oscillations) are proposed. The problems of origin of angle mixings, with the law of energy-momentum conservation and disintegration of neutrino as wave pocket are solved. These two schemes belong to mass mixings schemes, where mixing angles and oscillation lengths are expressed via elements of mass matrix. The third scheme belongs to the charge mixings scheme, where mixing parameters are expressed via neutrino weak charges, as it takes place in the vector dominance model. Using experiments we must decide which of these schemes is realized indeed. Analysis of the resonance enhancement mechanism of neutrino oscillations in matter is performed. It is shown that there are no indications on existence of this effect. It is shown that the supposition that the neutrinos are Majorana particles is not confirmed by accelerator experiments. Then only mixings (oscillations) between Dirac neutrinos with different flavors without sterile neutrinos can be realized. Using all the present experimental data and the theoretical results the problem of Sun neutrinos deficit is analyzed. The conclusion is: the primary Sun $\nu_e$ neutrinos are converted into mixtures of three types of neutrinos $\nu_e, \nu_\mu, \nu_\tau$ in approximately equal quantities.
