I suggest you create a single account using the supplied 000webhost subdomain name, and then park your domains on that account.
All your domains will then point to the same files without any coding or redirection.
You may, however, find that this course of action is disadvantaged in
SEO terms, so you might want to divert all your domains into one.
.htaccess will do that for you, example..
Code:
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !jockitdesign\.com$ [NC]
RewriteRule ^(.*)$ http://www.jockitdesign.com/$1 [L,R=301]
