The rate coefficients for the chemi-ionization (CI) processes in Na^★(n) + Na, Li^★(n) + Na, Li^★(n) + Li and H^★(n) + Li collisions are calculated for wide region of temperatures and the principal quantum numbers. The presented values of the rate coefficients are very useful for the improvement of modelling and analysis of different layers of weakly ionized plasmas in atmospheres of various stars where these and other CI processes could be important and could change the optical characteristics. Also, the results are of interest in spectroscopy of low temperature laboratory plasma.
