I'm pretty sure they get their names due to the Maidens being able to manipulate the elements:

The Winter Maiden: Ice and Water

The Spring Maiden: Water (I imagine like the seasons themselves, the maidens powers can overlap-- like how Amber used fire and ice) and Earth

The Summer Maiden: Earth and Fire

The Fall Maiden: Fire and Ice
