Setting up htaccess 404 error. How to do it right?

Question

Apache HTTP Server

There is something like this in the url: site.ru/news.php?id=1
And I want it to be site.ru/news/1
I wrote the following
RewriteRule ^news/([^/]+)/?$ news .php?id=$1
Everything works, but when you go to the site.ru/news.php link, it goes to site.ru/news and a 404 error is issued
How to register another redirect from site.ru/news.php?id=1 to site .ru/news/1
and from site.ru/news.php to site.ru/news

# 301 --- http://www.mydefile.ru/company/?a=47071 => http://www.mydefile.ru/about/
RewriteCond %{QUERY_STRING} (^|&)a=47071($|&)
RewriteRule ^company/$ /about/? [L,R=301]
