OK, so you know how to understand how your .top files are describing the nonbonded interactions between your atom types. Now you just need to combine the two. Probably you want one atomtypes section, etc. If you want them to interact, then you'll need to define parameters accordingly, either using combination rules (see manual) or with explicit nonbond_params (see manual).

I have .top and .gro file for both A and B atom types . how can I mix this two atom types ? do I must regard the lenard jones potential between this two atom type or not? and where I must put C12 and C6 parameters for interaction between these two atoms? Have you done the necessary background reading in chapters 4 and 4 of the manual?
