Q: May I trade my iPhone 6 with iphone 7 ?

No trade-up program for the iPhone 7 has been announced. However, if the existing program carries over then you can trade one working one.

They give you money if you take iPhones to an Apple Store. iPhone 7 is 649 US$, so 2 iPhone 6 + 1 iPhone 5S = 575 US$, only 75 US$ left. If you want to check that those iPhones are acceptable go here:

Hi

Depending on your location, Apple may offer instant in-store credit when trading in eligible iPhone models or an Apple Store Gift Card when trading in your devices by mail. Note that, at present, the online tool for checking trade-in value does not include the iPhone 6s.

You may also wish to consider the option of selling your various iPhone models privately and putting the proceeds towards your new purchase.
