No. Buying and selling sacraments is the sin of simony, which the Church condemns.
Catholics do not take communion, they receive communion.
Until they are baptized, they are not Catholics. Only Catholics may receive communion in the Catholic Church.
The Church of England allows Catholics, and I presume others, to receive communion out of a "spirit of Ecumenism." Whilst they allow this, a Catholic should not partake of communion with any "church" which is not in communion with Rome; as to do so, is an explicit consent to the believes and teachings of said "church." Please see the link below for a full explanation as to why it is wrong for Catholics to receive communion in a Church not in communion with Rome.
In the Catholic Church non Catholics may not receive communion without a special dispensation from the Bishop. Catholics in the state of serious sin may not receive communion.
Yes, and they use wine at communion.
Only Christians and Catholics do.
In communion Catholics receive the body and blood of Christ under the form of bread and wine.

Catholics do not TAKE Holy Communion, they may only RECEIVE it from a priest or a licensed Eucharistic Minister.
Because one of the reasons for receiving Holy Communion in the Catholic Church is to publicly show your communion with the Catholic Church. Non-Catholics are not in communion with the Catholic Church and therefore cannot receive Holy Communion.
No because receiving communion in the Catholic Church is not only a sign of love, but a communion of Catholics partaking in this sacrament of our redemption by Christ's death.
Yes, they can.
