Just like atoms are, lone pair electrons are also considered in the electron density. Their high repulsion force causes them to act slightly different, causing 2 electron pairs needing to be as far away from eachother as possible in a structure.
I think one lone pair of e- is counted as one electron density. So for example, like H2O, on the oxygen atom, there are two lone pairs of e- and we say there are four electron density clouds, 2 bonding and 2 lone-pairs.
Hope it helps!

Yes, lone pairs are considered their own regions and they repel other regions strongly too. That is why when looking at the shape of molecules we have to consider lone pairs (because they repel the other bonds).
yes they count as their own separate region and have a stronger repulsion power than the rest of the regions. the powers go from lone pair to lone pair>lone pair to bonding pair>bonding pair to bonding pair. This will in turn also cause the angles between the other regions to be greater.
lone pair e- do count as their own regions of electron density, including when you are creating a VSPER model. In addition, e- are more repulsive compared to bound atoms, which in turn affects the bound angles of a molecule.
They most definitely do! in terms of the magnitude of which molecular geometry is affected by other regions of electron density it goes as follows, LP-LP, LP-atom, atom-atom. Lone pairs are not shared and essentially belong to the atom which the LP is assigned, which is why affect vsper so much.
