Webhosting service
 

Which one would you suggest me?
I heard bluehost is the best hosting service but hostgator is good too and is cheaper.
All I want is a fast webhosting service with unlimited storage/domains/subdomains/emails. If they met those requirements, I prefer to chose the cheapest one.

Any suggestions?

Bluehost and Hostgator are both part of EIG and are quite terrible.

I would recommend keeping your hosting and email separate and going with at least Google Apps for Business or Microsoft Hosted Exchange. $4-5/mailbox/mo and you can add as many aliases and domains to it as you like.

If I was going to recommend shared hosting I would likely go with Nixihost or Veerotech.

Is Nixihost giving free domain forever if we buy the professional package?

It's likely renewed every year as long as you have a subscription with them. I also recommend getting your domain from a registrar (Namecheap, Gandi, etc.) rather than through the web host.
