Who is ahmindra
If you mean Ahamindra in Jainism, it is a term for a very exalted heavenly being in the higher celestial realms, especially the Graiveyaka and Anuttara heavens. In Jain texts, an Ahamindra is described as one who realizes, “I am Indra myself,” meaning there is no lord above him in that realm. ( wisdomlib.org)
In simple words: an Ahamindra is a highly elevated deva, not a liberated soul or Tirthankar. ( wisdomlib.org)
