How to put forward a blog post

I would know if I can put forward a blog post natively using Wordpress ?

For example, I have created 20 posts, but I only show 5 on my homepage. Then imagine that I want to put the 18th at the first place ? By default Wordpress order by publication date. I was thinking about creating a custom field called for example 'highlighting' with a boolean value and order by this new field, but it has its limit if there is more than one post to 'highlight'.

So my exact question is: There is a native way to this with Wordpress ?

Thank you in advance.
