How to add hydrogen atoms to carbons that have disordered bonds during structure refinement using Olex2?

Say a particular carbon atom is bonded to three other nitrogen atoms (disordered over three sites with 1/3 occupancy), Olex2 doesn't allow to geometrically place hydrogen atoms on this particular...

During structure refinement in Olex2, I see periodic Q-peaks along the bonds (i.e., in between atom pairs). What do they generally imply ?

During structure refinement, relatively intense periodic electron density Q-peaks appear along the bonds between atoms. What do they imply and how to go around them ?

Is Hall coefficient measurable for a system whose d.c electrical conductivity is governed by carrier hopping?

if electrical conductivity near room temperature is dominated by say thermally activated carrier hopping, then is it possible to measure Hall coefficient near room temperature ?

What is the relation btwn the sign of reduced chemical potential and position of Fermi level i.e. in the band gap or inside the band of a semicond. ?

While describing the electrical transport using single parabolic model, it was mentioned in a couple of papers that a negative value of reduced chemical potential (u
