JRRT was not totally consistent (hard to be over the course of seventy-odd years) but I've never seen anything where he referred to her as a queen or allowed others to do so. Gimli does call her "Queen Galadriel" but he's a Dwarf and could just be describing her Dwarf-fashion; after all, Dwarves aren't exactly big on downplaying their titles. (e.g. Thorin, "Say that the King under the Mountain has returned!" when technically he wasn't in charge of anything except for a dozen waterlogged Dwarves). It's easy to imagine dropping a Dwarf's title as being very disrespectful, and of course since Gimli loves Galadriel he would never dream of calling her by anything less than the highest title known to him. And frankly, what with the axe and all, it's hard to imagine anyone trying to correct him.
