Yes, just make sure to specify the 'image' keyword with the 'hbond' command.

Use the 'density' command with an atom mask selecting the atoms you
want. Check the manual for full details on both the 'hbond' and
'density' commands. You can look at the tests for each command (in the
$CPPTRAJHOME/test or $AMBERHOME/AmberTools/src/cpptraj/test
subdirectories) for additional examples (Test_Hbond and Test_Density
respectively). Hope this helps,
