Duplicate main page – another blog page

Hi, please advise me on the following: I would like to have another page on my site which functions just as the main page does, accepting blog posts.
It not much of a help, but my site is https://lakasmuhely.hu – it is all in weird Hungarian though.
I details, I would like to have a community to share their posts on the Blogok (blogs) page, and me being able to promote the ones I like to the main page. So I would need to
– duplicate my entire main page
– have the option for admin users to flag posts as “main page”
– retain original posts on the Blogs page
– have the option for admin users to post where they want, either main page or Blogs.

Is there a way to do all this?
Thanks so much in advance.
