The succession now is limited to the legitimate/legitimatized descendants of Rainier III - or Albert, Caroline, Stephanie, and their descendants (with some exceptions).
If Albert were to die, then the succession would become his legitimate/legitimatized descendants - or Jacques and Gabriella. Everyone else in the succession would be removed from the succession.

Jazmin is ineligible because of the nature of the affair that lead to her conception - her mother was still married to another man, so she can't be legitimatized under Monegasque law.
If Albert were to marry Alexandre's mother, though, not only would Alexandre be in the line of succession but he would also be above Jacques and Gabriella (as he's male and older).
