The MASS section is the same in all of the different topology files. In principle you could delete some of the unused atom types, but there's little point in doing so. Hydrogens are of course defined in the RESI sections in the all-hydrogen topology (top_allh.lib).

This means that the FE and NA atoms in the HEB residue don't have atom classes defined. Atom classes are defined in modlib/atmcls-melo.lib and are used for statistical potentials (see http://salilab.org/modeller/manual6v2/node43.html) Since you probably don't care about loop modeling of the HEB residue, you can ignore these warnings.

You have defined a restraint which contains one or more atoms which don't exist in your model. Check your restraints file.
