Yes they do, but you have to take into consideration the integrity of the chip embedded with the tag body, bending the tag close to 90 degrees will probably damage the device.

Q: How long does this device last? Does it require batteries?

Like others have said, no battery required. NFC chips have lifespans measured in numbers of read/write cycles. For this particular chip (NTAG213) read/write endurance is 100,000 cycles. This means it will likely function for the entire time you would be using it.

Q: Can i use more than one at a time. For example stick 2 on the back of my phone and have each set up to do different things?

In a word, no. In three words, yes and no.First, you shouldn't stick these onto the phone.These are a specialized type of RFID(Radio Frequency Identification) tag commonly referred to as a NFC(Near Field Communication) tag.Basic operation is as follows:1. A device(eg. your phone) sends a signal (kind of like a ping) to any tag that might be close enough to "hear."2. The tag hears the ping and responds with the information contained on the tag.3. The device uses that information in the way it was programmed to use it.Communication in steps 1 & 2 is actually a lot more complicated, but basically you need to understand that the device will only talk to one tag at a time. The app you use will only process commands tied to one tag at a time in a serial fashion. Most apps will allow you to tie multiple commands to one tag, so you shouldn't need to have multiple tags stacked up.

Q: Will these tags, or any tags work on a magnetic phone holder(like the ones for your car)?

Yes they will ! Our tags have a anti metallic shielding - this enables them to work on metallic surfaces as well as in proximity to magnets.
