No, a minecraft account is not free. You must buy it for around $25.00 or so U.S. dollars. You pay only once, and once you buy it you can change your skin on the website and download the free Minecraft client.
Yes, however, to play the Minecraft Beta you must purchase it with your credit card. If you would like to get a feel for the game for free you can play Minecraft Classic which is a creative mode where you are given an unlimited amount of 9 different resources to build with. WARNING: Please note that Minecraft Classic is different from the Minecraft Beta's Survival Mode. If you find Minecraft Classic boring and would enjoy something more challenging, I encourage you to purchase the Minecraft Beta.
For Classic, yes. It's required if you want multiplayer or the full Minecraft, which is not free.
No.
Minecraft accounts are free to register.
Anyone can register a free Minecraft account on the Minecraft website.
Yes!

No. I don't believe so. Plus register is free so why don't you just register.
No, it's completely free to register. It only costs money if you choose to buy the game.
Minecraft accounts are already free, you can freely register one. You only need to pay if you want the full version.
They're free to make, go ahead and register one.
When you register for Minecraft, you have a free account. You can play the free Classic online version. You can still download the Minecraft launcher, you just won't be able to play it without paying for it first. Once your account is premium you can log into the launcher (that you downloaded) and it will download the rest of the game.
You must register your account to play Minecraft, however, anyone can download Minecraft.

The signup for a Minecraft account is free. But purchasing Minecraft (or getting a premium account, however you want to say it) is not free, unless somebody gives you a gift code. As of right now, I believe Minecraft is around $27 to buy. Note: Downloading Minecraft is free. But if you log into the Minecraft launcher without purchasing Minecraft, it will say something like "User not Premium".
