I doubt you will find a free multiple host domain. You might find some free hosts that allow a single domain but mostly allow subdomain or subdirectories.

i do not need to host al of them just one.
have a link for one?

Hi! We can provide you with one of our Package for free. I can give you our HaH plan which includes:
Unlimited Email Addresses
Unlimited MySQL Databases
Unlimited sub Domains
Unlimited Park & Addon Domains
Cpanel 10.2 & Fantastico
24/7 Live and Ticket Support!
150 MB Space

As your site gets bigger, we can upgrade you to our Magnetic plan for free.
But since you are hosting multiple sites, we are only asking to put one of our small banner anywhere on one of your site

Have fun!
