Oh, oh I hope it's alright if I post a few screenshots from the show itself and describe some of the characters. Not really spoilers.

Twilight Sparkle. She represents the Element of the Magic of Friendship. She simply loves Libraries, books, reading, studying, practicing Magic, etc. but she'll also help out her friends if ever they needed her. No matter how hard the tasks that were trusted upon her seemed, even if they made her go crazy with worry, in the end, she and her friends could solve it.

Pinkie Pie. She represents the Element of Laughter. She loves throwing parties for her friends and making everypony smile, even when it sometimes makes her look silly. But, for her closest friends, she would do anything no matter how hard it was for her. Even watching paint dry.

Rainbow Dash. She represents the Element of Loyalty. She loves soaring in the sky like her idols, The Wonderbolts. Flying fast and strong, she loves competition but treasures friendship even more.She would never leave Ponyville or any of her friends hanging. She can be there for them in ten seconds flat.

Applejack. She represents the Element of Honesty. A strong, tough mare who loves helping ponies around her, Applejack is a pony you can count on in dark times. She's down to earth and would rather choose function over form, but her family and friends matter the most and she won't let her personal feelings get in the way of problems that they could solve together. Like maybe if a tree fell in your house.

Fluttershy. She represents the Element of Kindness. As her name implies she is a shy pony. She also has fear of flying, dragons, the forest behind her house and her own shadow. But that doesn't stop her from being assertive when her friends need her the most. In fact, she'll stand up to just about anything and send critters scurrying off with a single stare.

Rarity. She represents the Element of Generosity. A dress-maker in Ponyville, she loves making new dresses for all her friends, especially if there are occasions for it. Sometimes her love for gems and fashion gets the best of her, but she would never allow it to come between her and her friends. Especially not after Tom.
