Redirect - 4 total parameters - .htaccess

Question

#anubhava and #RavinderSingh13 have continued to help me learn and progress to where I am today with this script. This is what I have so far:
##1st rule with one parameter: $id--
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} id=([0-9]+) [NC]
RewriteRule ^file\.php$ /directory/%1? [R=301,L,NC]
RewriteRule ^directory/(\d+)/?$ /directory/file.php?id=$1 [L,QSA,NC]
##Parameters are $id and $class
RewriteCond %{THE_REQUEST} \s/file\.php\?id=(\d+)&class=(\w+-class)\s [NC]
RewriteRule ^ /directory/%1/%2? [R=301,L]
RewriteRule ^directory/(\d+)/(\w+-class)/?$ /directory/file.php?id=$1&class=$2 [NC,L,QSA]
##Rule with two parameters: $id and $name--
RewriteCond %{THE_REQUEST} \s/file\.php\?id=(\d+)&name=(\S+)\s [NC]
RewriteRule ^ /directory/%1/%2? [R=301,L]
RewriteRule ^directory/(\d+)/(.*)/?$ /directory/file.php?id=$1&name=$2 [NC,L,QSA]```
Now, I would like to add one more rule with only one parameter instead of two. However, this parameter uses PHP $_GET['name'] in the url. I am trying to add one more rule that rewrites http://IPADDRESS.com/file.php?name=JohnDoe to http://IPADDRESS.com/newdirectory/JOHNDOE.
Thank you!
