How many times will apple replace my iphone?

I got my first iPhone last September and in December i had to get it replaced because a spring in the headphone input thing broke off. Now, the sleep button is starting to stick and it has some storage problems. I didn't do anything to void to warranty of it and i haven't dropped it or cracked it or anything. Will they place this phone FOR FREE, knowing that I have already had to get one replaced? Both problems aren't my fault so if i have to pay for a second one i will be mad lol. And I also already know about the sleep accessibility button.

Added (1). Also, don't be like "androids are better just get one of those" lol no those are too confusing and that's not the point of my question

Changing my Iphone and using ICloud?

So I have an Iphone 5 and I'm planning on changing it for a new one because I think the sensor thing is not working well. If I get a new one with the guarantee, how do I use I cloud so that all of my apps and pictures will be on the new iphone. I don't have photo stream on because I don't want my pictures going on other devices with my icloud username. And I have the app: photo vault which keeps pictures " hidden" by requiring a password to see them, so how will I ensure to know all of these secret photos and apps and pictures with no photo stream on will be on the new phone?
