H-NMR Clarification

[marymatthews]

For H-NMR I am having trouble understanding what happens when the Hydrogen on the adjacent carbon is "identical", do you count it in the n+1 rule?
If a carbon has a Hydrogen on it, and the neighboring carbon has the exact 'same' Hydrogen, is that "identical" Hydrogen factored into the n + 1 rule as an additional H or do you not count it?
So if a hydrogen has only 1 identical hydrogen on the adjacent carbon, would it be a singlet or a doublet?

Also, lets say there is a hydrogen on a carbon, and there are two identical hydrogens on opposite sides of this hydrogen (but not different than this Main hydrogen)
so basically two hydrogens that are identical are on adjacent carbons of a dissimilar hydrogen, would the two same hydrogens be considered 1 or 2 additions to the n + 1 rule?
So if a hydrogen has two hydrogens that are identical to each other on opposite adjacent carbons, would this hydrogen be considered a doublet or a triplet?
Thanks

if a hydrogen has ONE adjacent hydrogen that is NOT IDENTICAL, then it'll be a doublet. (n+1 rule)
if there are ONE, TWO, THREE adjacent hydrogens that ARE identical, then it'll be a singlet, but it'll integrate to more area.

Thanks
what if there is are TWO hydrogens that are idental which are adjacent to a third non-identical hydrogen? what will be the splitting of this THIRD hydrogen?
Basically one hydrogen(a) has two hydrogens(b, b) that are identical to each other only on opposite adjacent carbons, would this hydrogen be considered a doublet or a triplet?
