I don't want to say my highnesses the servant is greeting a princess and a queen, what other way can i greet both without saying them seperately or saying highnesses/eminences/majesty's etc?
Debretts has a full set of sub-pages about how to address various members of royal and aristocratic families. Generally, a queen and a princess wouldn't have the same form of address anyway - the queen would go by "your Majesty", while a princess gets "Your Royal Highness", so trying to refer to any of them in the plural would already be wrong. Personally, I got around it by having my main POV character in those scenes be someone who absolutely refuses to play the game, and just refers to them by their first names instead.
The queen is the majesty, and the princess is a royal highness, or your servant peasant type might be a dreadfully common person, overwhelmed by regal specialness, and blurt idiotic dribble, drool some basic words like 'take a seat, my ducks, I'll be right back in our best china cups, and our Nice biscuits, Mam, mam, mammy.' She breaks into song at this point, black-faced, completely out of era, frankly. Queen understands these kind of things. If the pleb is genuinely in a state of shock she can say pretty much anything in presence of our royalty, we comprehend foibles of the masses. A modern throne, going forward, if you like.
That would depend on your world's titles for royalty. If it were just a servant and princess it would be "mi'lady" or "your highness" however maybe you set up a different title for them depending on how they function, or what their culture signifies as important or even a characteristic trait that all those of royal blood have.
I'm pretty sure "Your majesties" would be the correct plural grammar, although if I'm mistaken, hopefully there's an English teacher or two on here to correct me.
I know you were probably baked when you wrote this, but I genuinely love it too. It gets old when, in fantasy, everyone is constantly formal and solemn and into their ultra-serious customs and blah blah. It would be more fun and fresh if the people at the top were more chill.
...but my dear @fw I was not baked, mashed, strung out, wired, fried. I was on fire, firing on all cylinders, fresh-faced, gurning all the same. # For goodness sake...
