The "area" is a number that you find on the Transition Result in the Document Grid.
The "total area" is on the Precursor Result. It is equal to the sum of the all of the peak areas for the transitions under that precursor.
We do not recommend using the "Total Area Normalized" for anything. It is equal to the Total Area divided by the sum of all of the areas of all of the other things in the replicate. This column existed in Skyline long before Skyline had any features which allowed you to specify different normalization methods.
Skyline does have a useful normalized area column. It's called "Normalized Area" and it is on the Precursor Result
Proteins > Peptides > Peptide Results > Quantification > Normalized Area
That column has the area for the peptide normalized based on your settings at:
Settings > Peptide Settings > Quantification
The CV values that you have in your screenshots are coming from the "Precursor Result Summary" group of columns in the Document Grid.
If you want more control over how the CVs are calculated, for instance, if you want your replicates to be grouped by cohort first, you can take a look at "PivotEditorCalculateCVAcrossCohorts.pdf" on the Pivot Editor tip page:
