Charmed is a TV show about three sisters: Prue (Shannen Doherty), Piper (Holly Marie Combs) & Phoebe Halliwell (Alyssa Milano).

After their grandmother dies, they find out that they are the strongest witches of their time, and they recieve their powers.
Prue recieves the power of telekineses, which means she can move objects with her mind or the wave of her hand. Like this:

Prue later recieves the power of Astral Projection.
Piper recieves the power of Molecular Immobilization, which gives her the power to freeze time. Like this:

Piper later recieves the power of Molecular Combustion.
Phoebe recieves the power of premonition and can then see future events:

Phoebe later recieves the power of levitation. She also becomes an empath.
Shannen Doherty (Prue) decided to leave the show after some time, which meant that her character had to be killed off. That's when they brought in Rose McGowan to take the role as Paige, the sisters' half sister who is also half witch and half whitelighter. It was neccessary so the "Power of Three" wouldn't be broken up.
Paige recieved the power of Telekinetic Orbing, along with other whitelighter powers:

As for the men of Charmed. There is...
Andy Trudeau (Prue's High School Sweetheart - a cop)
Darryl Morris (Good friend of the Halliwells - a cop)
Leo Wyatt (Piper Halliwell's husband and the father of her children. Also the girls' whitelighter)
Cole Turner (Phoebe Halliwell's first husband - a demon)
Chris Perry Halliwell (Piper's 2nd son, who came back from the future)
(And I haven't gotten much further in the series. But I believe that the guys Phoebe and Paige end up with are known as Henry and Coop. Henry is a mortal and Coop is a Cupid.)
