This is not a contactless device. It uses a common 1-wire protocol.

Some can, some can not.
Without knowing specifics it is hard to say.
Some systems use the UID which is hard coded during wafer fabrication. I'm not aware of mechanisms around this.
Worth mentioning that I have not spent any time researching this for years. I'm not an expert on the subject.

I copy them using the Smartcard Deluxe machine. there are other machines on the market that are cheaper and can copy them though.
RMX Labs in Russia make a few different ones and a google search will bring up some other machines out there.
