Lauric acid is a long chain fatty acid of formula C12H24O2 with melting point of 44 C.  Stearic acid is another long chain fatty acid of formula C18H36O2 and melting point of 69.6C.  To mix them you would have to weigh out the amount of each desired in the mixture and heat gently to melt and stir to mix.  When they cool again you will have a homogeneous mixture of the two with a melting point somewhere in between depending on the ratio of the two in your mixture.  There will be no chemical reaction between the two when mixed.
