Dame is the excepted, Lady is the promotion and as stated before ma'am is the contracted form of m'dame or madame (which also works for madameoiselle)….
Lord/Lady; Duke/Dutchess; Baron/Baroness; King/Queen; Prince/Princess; Sultan/Sultana (or Sulteema); Viscount;Viscountess; Count/Countess(a); Father/Mother; Cardinal; Pope; Bishop; Imam & Baronet are all Titles - terms that denote special honor and are to be used at all times to show deference to that position….
(I'm sure there are more but its late and I'm tired)
So I hope that you won’t mind a few corrections, if we’re speaking English, we should probably use English, or British terms.
In descending order below Kings Queens, Princes and Princesses come:
Duke/Duchess (no ‘t’) in Dutchess, not even for residents of the Netherlands.
Marquis/Marchioness (which you missed completely)
Earl/Countess (Count/Comte, etc are invariably ‘foreign’ titles). I won’t bore you with the reasoning behind these titles, we’ll just shrug our shoulders and accept that it’s correct English.
Viscount/Viscountess
Baron/Baroness
Lord and Lady aren’t really noble titles, they are how everyone below a duke is referred to in speech. The Earl of Westmoreland would simply be called, Lord Westmoreland. Obviously

the Earl of Caithness, would be referred to as Laird Caithness, because he’s a Scottish Earl.
Knights of the realm stand below Barons and are called Sir (or Dame) ‘forename.’ Never Lord, because they aren’t.
