Is it wrong to worship Zeus ,Apollo, Aphrodite, Hera and Pluto ?

If you entered into an agreement as the early, Pagan and polytheistic Jews did, to become monotheistic and "worship" only one god, yes, it would be wrong. It would make you an oath breaker. However, if you have no such covenant then there is nothing wrong with it whatsoever. However, it should be noted that Pagans and Heathens do not "worship" like the Abrahamics do. We look our deities in the eye, take full responsibility for all of our actions both good and bad and do not grovel before anyone or anything. We are to stand proudly before our deities. We honor them, just as one would honor an older relative who was smarter and stronger than you, and that is what is expected of us. Groveling, begging, being a god-botherer - all of those things are considered dishonorable behaviors and indicative of cowardice, things strongly frowned upon in my own faith. So no, do not "worship" them. Simply honor then appropriately if you wish. If you do not feel drawn to them, then ignore them. I can guarantee they will not care one bit.
