Any Limitation on Archieve or pages in wordpress?

No limitation except what might be imposed by your hosting company.

To make WordPress available at https://www.college.com in Settings->General, change the Blog address (URL) to https://www.college.com and put this index.php file in your web-root folder (it is the same folder that contains the wp folder)

<?php
/* Short and sweet */
define('WP_USE_THEMES', true);
require('./wp/wp-blog-header.php');
?>

Then update your permalinks by visiting Administration > Settings > Permalinks and clicking on Save Changes.

Thanks for your assisance, I really appreciate it ??

Have a good day
