Para- comes from the Greek para, which means "beside", "next to" or "beyond". It shows a side-by-side relation: something that goes alongside, accompanies or resembles another thing.
Para- changes its sense a bit depending on the word. Sometimes it is "beside", like an assistant who works next to a professional. Sometimes it is "beyond", like something outside what is normal or official. And sometimes it is "similar but not the same", like an imitation. It is one of the most versatile Greek prefixes, so it helps to look at the context of each word.

By definition, a parasite harms or at least fails to benefit its host. Not all organisms that "depend" on others are parasites: mutualists benefit each other; commensals benefit without harming. Only the parasite benefits at the host's expense.
"Paranormal" (para- = beyond + normal) describes phenomena outside what science currently explains (ESP, telekinesis). "Supernatural" (super- = above + natural) implies an intervention from a higher order, typically divine. They are related but not identical concepts.
A trick to remember it
Picture something walking alongside the main thing, like its helper: para- = next to, auxiliary. paramedic, paragraph.
