.htaccess advanced redirects

Hi, need help understanding how to redirect properly through .htaccess.

I want to redirect:
1. exact-oldpage to new domain page
2. all-trash-oldpages-with-links to new home page.

What I do:
Redirect 301 /exact-oldpage https:/domain.com/new-domain-page

But then I tried different ways to redirect, such as adding in the end:
RedirectMatch 301 ^/.*$ /

But all of those ways redirecting everything including pages with rules.
