What iphone type is the best and easiest to use? IPhone 4,5.or6? - 1

IPhone 4 is pretty good to use.

I would recommend the iPhone 6. I have one and it is very easy to use with many functions. It is the most user-friendy, supports the most app, and has the most features. You will need to probably spend a little more, though. Pricing may have to be taken into account.

IPhone 6s is the best with 2GB of ram and 12mp camera and many cool features like 3D Touch

Latest version is obviously best and newest hardware out

The best of course is the latest, the 6s/6s Plus
Easiest to use, they are all equal in that regard, unless you take 1-handedness in mind in which case the newer 6, 6 Plus, 6s, 6s Plus wouldn't be as easy since they are bigger.

Easy, I can't say but always prefer to get the latest device and If you need to have a good security app, the best app for securing your personal images and videos and also to lock various applications of yours would be Leo Privacy Guard.
