[Star Wars] What succession mechanics are in place for Alderaan (and Naboo, to a lesser extent)? Would the children of Princess Leia hold or have a claim to any royal titles?

Well, in the case of Alderaan, it's all House Royalty. She was a Princess of House Alderaan, but not Princess of Alderaan itself. Hence why her father was both a Crown Prince and a Senator. 

Naboo actually elects their Royalty. Padme became a senator after her term as Queen was up.
