Questions about Indra

In all hindu religious shows I've seen, I notice that they show Indra, his wife Sachi, and his mom, Aditi. However, I've never seen or heard of a father?

Who is Aditi's husband.....Wasn't there ever a time when Indra was the prince of heaven.......and Aditi's husband was the King...??? Also, how many siblings does Indra have??? I heard the Sun God is one of his siblings.

In brief let me say that Indra has many siblings. Sun god is one of those. Vaman(Vishnu's dwarf incarnation) is also Indra's brother.

Indra's father is Kashyap.
Kashyap is the son of Marichi and Kala.
Marichi was created by Brahma. Kala is the daughter of Kardam and Devhuti.
Kardam was created by Brahma. Devhuti is the daughter of Swyambhuv Manu and Shatrupa.
Swyambhuv Manu and Shatrupa were created from Brahma's body.

You also asked if there was a time when Indra's father was king. The answer is no. Indra's father Kashyap was never a king. He always lived like a sage in his ashram. You may ask who was the king of heaven before Indra was born. The answer is that when heaven was made, at that time Indra had already been born and was qualified to become a king. Swarg(i.e. heaven ruled by Indra) is temporary; it is not eternal.
