Telus Iphone family plans?

Hey so I'm going in town tomorrow to hopefully pick up two iphone 5's, for me and my brother. Here's my question, and I apologies I'm a little foggy on how "Family Plans" work.

Best Buy has iPhone 5's on for $0 on a three year plan. What I WANT to try and do being a poor collage student, is to get the promo 70$ a month family plan, and share it with my brother.

Do you guys have any idea if I'd be able to get TWO free iPhone 5's with the ONE plan? In all modesty my dad is a very good negotiator, so keep that in mind. Because then I'd be paying 35$ a month for the plan that has exactly what I want.

If not, what do you guys think IS possible? Could I get two free iPhone 4S's? or could we get two iPhone 5's for like 50$ a phone? I'm just trying to get as much info as possible before I go into the madness of boxing day. Thanks a lot guys, and Merry Christmas :)
