looking for an expanded multiple loops example

Hi, I need to create multiple loops on the home page. I’ve been reading the codex but the examples only go into two loops and I want to see how the code continues to do more.

there will be 8 different categories. for each category I want to display a list of only the titles of the last 5 posts.

I would like to use the method that utilizes update_post_caches($posts) to prevent conflicts with other plugins the site owner may add in the future. However I am not quite clear (the way the methods are layed out) where the rewind function fits into a structure like this.

Any help would be greatly appreciated. Thank you very much in advance.
