It's not really clear what you are trying to achieve.
When you say "convert dynamic urls to static urls", do you really want to have user to type in the ...?id=10
and the file named Barbara_Mori_Hrithik_Roshan_New_Movie
lives on your server? I think, it's the opposite way - you want to let the user type in the long & nice title and actually resolve it to ?id=10
If this is the case, the @Mike's answer is nearly correct, you only have to swap the parts of the last line:
RewriteRule Barbara_Mori_Hrithik_Roshan_New_Movie stories.php?id=10 [R,L]
Another question - are you sure you have the .htaccess working? An easy way to check is to set the contents of .htaccess to
order deny, allow
deny from all
And see if you can still access that directory. If you can, this means the "deny from all" does not work. Then check your apache config - is .htaccess allowed in the particular virtualhost and/or directory.
