I wear a 6.5 and after scrutinizing all the lovely pics here for my future reference, I think you will need .25 to .3 ct stones in a shared prong setting, for 1.25 to 1.5 ctw in the whole ring. If its bar set you may be able to get away with 1 ctw to 1.25 ctw.
I think an impressive 5-stone band is a lovely ring to wear and I love love love the profile of the some of these rings where you can see the stones so well. I would really encourage you to go that route (rather than a 7-stone band) if you can afford it.
I myself would have been very happy with a 5-stone or a shared prong eternity engagement ring if budget restrictions were a factor. HOWEVER it is a personal preference - one of my friends would clearly prefer her bf spend his limited $$ on a 0.5 ct solitaire - she prefers a traditional look even with a smaller center stone.
Like any gift, a thoughtful gift giver should take some care into getting something that suites that tastes and preferences of the receiver. If the OP has not consulted with his gf on her e-ring preferences, and does not plan to do so to preserve the "surprise" element, he should carefully think about whether SHE would want a 5-stone engagement ring or is a more traditional gal. Obviously he knows her and we do not, but we can just remind him to procede cautiously IF she''s not already aware of his plan.
Good luck.
