How to auto populate posts to a page

I have all of my posts either a) be posted onto the main section of the webpage or b) be posted to one of the other 4 sections of my website. Is there a way for all of my pages to be posted on the homepage scroll and then have them, depending on the category I choose, auto-populate to the other section of my website so I don’t have to post them myself in two different places? Thanks!
