In Jainism, a Chakravarti’s chief queen is called Patrani. A Chakravarti is also described as having many queens, but there is no single fixed universal list of queen names for all Chakravartis in the way there is for the 12 Chakravartis themselves. ( jainknowledge.com)

If you mean a specific Chakravarti like Bharata or Sanatkumara, then the queen names differ for each one. For example, Jain sources mention Sahadevi as Sanatkumara’s queen. ( jainknowledge.com)
