We report the bivariate $HI$ - and $H_2$ -stellar mass distributions of local galaxies in addition of an inventory of galaxy mass functions, MFs, for $HI$ , $H_2$ , cold gas, and baryonic mass, separately into early- and late-type galaxies. The MFs are determined using the $HI$ and $H_2$ conditional distributions and the galaxy stellar mass function (GSMF). For the conditional distributions we use the results from the compilation presented in Calette et al. [(2018) RMxAA, 54, 443.]. For determining the GSMF from $M_{*}∼3×10^7$ to $3×10^{12} M_{\odot}$ , we combine two spectroscopic samples from the Sloan Digital Sky Survey at the redshift range $0.0033
