Answer 1

You rules will have to allow folder_name as well so use:
RewriteEngine On
# external
RewriteCond %{THE_REQUEST} \s/+(folder_name)/art\.php\?id=([^&]*)&s=([^\s&]*) [NC]
RewriteRule ^ /%1/%2/%3? [R=301,L]
# internal
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(folder_name)/([\w-]+)/([\w-]+)/?$ $1/art.php?id=$2&s=$3 [L,QSA,NC]
This assumes there is no other .htaccess in folder_name/.
In case there is a .htaccess inside that subfolder then use this .htaccess:
RewriteEngine On
RewriteBase /folder_name/
# external
RewriteCond %{THE_REQUEST} /art\.php\?id=([^&]*)&s=([^\s&]*) [NC]
RewriteRule ^ %1/%2? [R=301,L]
# internal
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([\w-]+)/([\w-]+)/?$ art.php?id=$1&s=$1 [L,QSA]
