How do you add more posts to a wordpress page?

Well I have my website and I have more than one page on my site. I know that with the main page (home page) you can add more and more posts by going into your dashboard and then on the menu to the side select- posts> add new. But what if I wanted to add more than one post to another page on my site? How do I do this? Each page on my site is going to need at least 3 posts on each page. Help is appreciated.
