Of those only the Prada is close, and even then the similarities are very superficial:
http://gizmodo.com/261172/settling-this-iphone-vs-lg-prada-n...Since it was released so close to the launch of the iPhone that it's not like Apple could have possibly dropped everything and rebuilt their entire design strategy around it. The protracted lawsuit with Samsung showed how Apple had been working on that design for some time and had already settled on a number of key design elements, the "rectangle" being one.
Those are interesting historical artifacts, but none of those had any lasting impact on the market, they were merely historical curiosities that nobody ever copied.

No, it doesn't give you an exclusive right per-se, but there's a lot of ways you can make a touch-screen phone short of copying Apple's design millimeter for millimeter like Samsung did.
So long as there's such a thing as a design patent then, legally speaking, yes, you do have the sole right. That's what patents are for. I'm generally not a fan of patents, but you can't argue that they don't exist.
There was incredible variety in the phone space prior to the iPhone, phones came in all shapes and sizes with vendors exploring increasingly implausible formats out of desperation. Post-iPhone they all converged, coincidentally I'm sure, on Apple's design. It's only now we're seeing some divergence from that.
Today we're seeing the same ridiculous convergence with keyboards where everyone plus dog is using the Apple layout. This hurts consumers since there's far little choice than there was before.
There's a huge difference between "copying" meaning "taking a good idea and giving it your own spin and making it even better" (e.g. Android vs iOS) and "copying" meaning "making a shitty knock-off version of a thing that looks almost identical to the other thing superficially", as in all the bargain-priced knock-off phones that are sold using Apple's branding (http://mashable.com/2016/06/17/apple-china-knockoffs/#qO0bF3...). Most companies fall in the middle here, but some skew very close to the bottom.
