I bought the online deluxe product, do I get 5 e-files

No, you do not.
When you use Turbotax Online version, you can prepare only one return per account/payment. This Turbotax help topic tells you how to start another return:

That is a fundamental difference between the Turbotax Online version, which you access through a web browser, and the CD/Desktop version which installs and runs on your home computer.
With the CD/Desktop version, you can prepare as many returns as you wish just for the price of the box.

The online program is a single use only product. Only the downloaded program has the ability to complete multiple returns.

 Never file a second return under the login you used to file your own return. Doing this overwrites (replaces) your original tax returns data and will cause future problems when retrieving or transferring your tax return.

Instead, create a new User ID/Password combination for the second return. Here's how:

    Sign out of TurboTax Online if you're still signed in under your login.
    of TurboTax Online if you're still signed in under your login.
    Go to turbotax.com and look for the New? Start for Free button or the Sign up link.

    If you can't find either one, you can also click here.
    Select the version you want to work on and select the Start for Free button.
    On the Let's Set Up Your Account screen, enter a new User ID/Password combination for the second return, along with the other requested info.
    After signing up, proceed with the second return.

It might be more economical to switch to the CD/Download Desktop software if you're planning to prepare multiple returns for family members.
