Question: how are the conjuring insidious and annabelle related?
Answer: It's a common question, but the answer is no, The Conjuring and Insidious franchises are not linked to each other. The only 'link' is James Wan who directed both the first two Conjuring movies and the Insidious films. Fun fact, Patrick Wilson starred in both the first two Insidious films and The Conjuring films.
