Not exactly.
For near field tags, a mu-metal shield provides some protection.
For far-field tags, the typical foil/screen Farraday cage provides protection.
Something is either magnetized or not magnetized. There is no such thing as "unmagnetized magnetic" material.
Magnetization does not affect the mass of the material being magnetized. All the magnetizing field does is align the magnetic domains of the material being magnetized. No matter or mass is added, or "created out of energy" or the like. Nothing changes except the orientation of magnetic domains within the material being magnetized.
Mainly from the electrons, rotating around the nucleus. If the material is magnetized, then it is because several atoms are aligned in the same direction.Mainly from the electrons, rotating around the nucleus.

Each material which can be magnetized has a material specific, so called Curie temperature. Above this specific temperature the material will lose its magnetism and the ability to be magnetized. Returning below this temperature, the material regains its magnetic properties.
Yes. When a material is magnetized the magnetic domains are aligned.
A block diagram of the RFID or radio frequency identification can be found online at places like TI.com and Colorado.edu.
The magnetic domains of an unmagnetized material will be pointing in random directions, which is why it is appearing to me unmagnetized. In a magnetized material, they move from north to south.

The domains in a magnetic material is aligned unlike the non-magnetic material which is scattered

If the other material is magnetized, then yes.
In non magnetized material the domains are not ordered -they do not align with one another.

The electron spin is actually a tiny magnet When a material is magnetized, the spins line up
saturation occurs when a magnetic material is as magnetized as it can get.
All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
