If you're asking what the oil is carried in, it's usually in a small metal container that holds cotton that has been saturated in the "Oil of the Sick." If you're asking what the "Oil of the Sick" is made of, generally it's plain olive oil with nothing added. Other plant based oils may be used if olive oil can not be obtained. The oil is blessed on Holy Thursday by the local bishop, or by any priest in cases of an emergency (this is rare.)
No, it is a Roman Catholic practice and is not Biblical.
Catholic AnswerIf you are a baptized Catholic, then you remain a Catholic your entire life. You might be a lapsed Catholic who is not attending Mass and services somewhere else, but that just makes you a Catholic who is not in a state of grace. Any Catholic is eligible for the Last Rites if they desire them, the first part of Last Rites is confession which means that you would be confessing your apostasy AND repenting of it. This is a very good thing, as you will die in a state of grace.

There are no other 'religions' in the Catholic Church. However, within the Catholic Church there are a number of rites, including the Latin (Roman) rite, the Maronites, and several Eastern rites but all are Catholic. They are not different religions.
The Last Rites for Catholic include several sacraments: Reconciliation/Penance/Confession, Confirmation (if the person hasn't received it yet ), Anointing of the Sick . . . and Viaticum (which is meant to be the last reception of Holy Communion for the journey from this life to eternity), along with the Apostolic Blessing, which carries a Plenary Indulgence (under the usual conditions).
