Yes, other religions that take communion are Orthodox Christianity, Protestants (Anglican, Lutheran, Baptist, Mennonites, Anabaptists, Reformed, Presbyterian, United Methodist), and Restorationists (Jehova's Witness, Latter-Day Saints, Seventh Day Adventists, Branch Davidian Seventh Day Adventists).
First of all, NOBODY can "take" Holy Communion, it may only be received. Secondly, only Catholics in good standing, and in a state of grace may receive Holy Communion. The Orthodox, and a few others who have valid Orders may receive Holy Communion with special permission of the local Bishop only if near death and no priest of their own Communion is available.
As a sign of forgiveness for their sins. Other religions besides Catholicism also receive the blessed sacrament of Holy Communion.

They celebrate more ones.
No, a lot of other religions say it too
No
In the Catholic Church only baptized Catholics who have made their first Communion and are in the state of grace may receive Communion. In the code of canon law, provisions are made for cases of emergency and necessity for members of other Christian religions to receive the Eucharist from a Catholic minister, but to do so, the recipient would have to believe in the sacrament and its theology and thus implicitly refers mainly to members of the Orthodox Church.
