Power of 5 (Book One, Charmed)

What if there were five Halliwell sisters instead of just three?
Poppy and Parker are twin sisters. They're younger than their older sisters, only 17 years old.
They're the ones that find the Book of Shadows, and recite the incantation that gives them and their sisters Prue, Piper and Phoebe their powers.
Prue was telekinesis.
Piper can freeze time.
Phoebe has premonitions of the future and the past.
And Parker and Poppy have influence over the four elements, only able to control one element at a time until they learn more about themselves and more about their powers.
With all of the sisters standing together, who can stand against the power of five?
