Hinduism....Can you name some of the Indra's?

There are supposed to be many Indra's, since scriptures say that Indra is a 'Pathavi' or 'Post' for the Ruler of heaven and not a person. Can you name some of the Indra's?

Why dint you try to use your thinking process to help you understand what a poverty stricken hell hole your country is because of the many religious movements , all of which encourage a fatalistic attitude to life in people such as yourself?

That's what I always heard, that "Indra" is a title and not a given name.

Yes. It is a post and a few names from Srimad Bhagavtam below:

During the reign of Svarocisa, the post of Indra was assumed by Rocana, the son of Yajna.

In this infantry, the name of Indra will be Atadhama, and the demigods will be headed by the Haritas.

To please V?manadeva, Bali Mah?r?ja risked defying the orders of his spiritual master, ?ukr?c?rya. Because of this, he would lose all his property, yet because of devotional service to the Lord, he would get more than he expected, and in the future, in the eighth manvantara, he would occupy the throne of Indra again.

Yes, it is a post granted to the ruler of heavens. As per Vishnu Purana, a single Manu rules an eon called a Manvantara and every Manvantara has a different Indra.
