Answer 2

These are the values for specific API levels, 11 and up, and 14 and up in this case. This means that you can override specific the values in specific versions easily.

Answer 3

You use the values-v11 and values-v14 folders in order to set up values (strings, dimens, styles, etc) for different android versions. For example, values-v11 targets android 11 and up. And you use the other two to target specific screen resolutions, and in the 2 case, a specific orientation as well.
