Which of the following Gods are also known as Lokapalas or the Guardians of the Universe?

In Hindu cosmology, the Lokapalas, also known as the Guardians of the World or Directions (Dikpalas), are deities who preside over specific cardinal points of the universe. The four primary Lokapalas guarding the cardinal directions are Indra (East), Yama (South), Varuna (West), and Kubera (North). While the Vedic pantheon initially emphasized gods like Indra and Varuna as supreme natural forces, later traditions such as the Manusmriti and various Puranas solidified the roles of these four as the primary guardians. Indra is the god of rain and thunder, Yama is the god of death, Varuna is the god of the oceans and sky, and Kubera is the lord of wealth and treasures. This group is often expanded to eight (Ashta-Dikpalas) to include intermediate directions, but the core four remain the most prominent guardians of the universe.
