What occults are in Indiana?

"Occult" is an adjective, meaning something hidden, it shouldn't be pluralized. This can refer to esoteric teachings of a religion (including Judaism, Christianity, Islam and other mainstream faiths), as well as the practices of other religions outside of the mainstream. This includes everything from divination (dowsing, tarot, astrology, ouija boards) to witchcraft in all of its forms, paganism, Satanism (LaVeyan and theistic), and so on...

So you'll need to be more specific in terms of the type of activities you're looking for in Indiana (though all of the above exist in some form or another throughout the United States, including Indiana).
