The exclusive semileptonic B -> K (1270) l(+)l(-) (l = mu, tau) decays are analyzed in variants of two-Higgs-doublet models (THDMs). The mass eigenstates K-1(1270) and K-1 (1400) are a mixture of two axial -vector SU(3) P-1(1) and P-3(1) states with the mixing angle OK. Making use of the form factors calculated in the light-cone QCD approach and by taking a mixing angle of theta(K) = -34 degrees, the impact of the parameters of the THDMs on different asymmetries in the above-mentioned semileptonic B meson decays is studied. In this context, the forward backward asymmetry and different lepton polarization asymmetries have been analyzed. We have found comprehensive effects of the parameters of the THDMs on the above-mentioned asymmetries. Therefore, precise measurements of these asymmetries at the LHC and different B factories, for the above-mentioned processes, can serve as a good tool to put some indirect constraints on the parametric space of the different versions of the THDM.
