What characteristics change when a loop antenna is made of a few turns -say 4- compared to a single turn loop of the same diameter ?

For loop antennas, you don't want to do that. The energy will just couple across the loops, you will not get better performance.

For NFC antenna, you increase or decrease the number of loops to get the inductance in the range of 0.8-3uH.
