You have two options:
1. Create virtual hosts and configure your server property files
2. Without creating virtual host simply remove contents of htdocs and paste wordpress files adn folders init
when you have to work another blog simply rename this htdocs to something else and create another htdocs and paste all files and folders of next wordpress blog.
Troubleshooting:
If you see blog error or database connection error makse sure to go to wp-config.php file under root and make sure following has correct value:
define(‘DB_HOST’, ‘localhost’); // 99% chance you
if you have virtual host your_domain.com and same url is in above line and if anyday you remove it from this file it’ll give you database error unless you typewrite localhost or keep that url in virtual host file.
