You’re making it very confusing with your terminology, which is non-standard to WordPress.
I wanted to know if you could put posts where you want them on pages. Like a static website works.
The usage of ‘posts’ here is incorrect. You don’t put posts on pages, even with a static website. You just don’t. So I’m going to assume you mean something else.
Do you mean a link? That is a way for someone to click on a word and go to a post, category, or otherwise?
Do you mean a menu? That would mean the menu at the top of the page would change content based on context. So if I was on the about page I would see one menu, and if I was on a category page I would see another?
Do you mean an image?
I’m very sorry to say that if you cannot help us understand what you mean by post, in the WordPress definition there of, we’re not going to be able to answer your question properly ??
