As others have suggested, get the official PSU (click the green BUY tag at the top of the page and scroll down to find it).
If you just want to try your new Pi out now, either of the first 2 on your list should work okay. The problem with some phone chargers is poor voltage regulation (phones don't need precise voltage control to charge). Also, if the charger uses a separate micro USB cable, the cable could be an additional problem (standard micro USB 2.0 cables aren't designed to deliver much more than 500mA without voltage loss). The cable that was included with the phone & charger should work better.

My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
