Part 1: 

None of these characters are pegasi but they have wings nonetheless:

• Turquoise, like pegasi, can summon his dragon wings and they take the place of his arms. He also has some nifty little claws. Instead of feathering, he gets scales around his shoulders and face
• Valiant, as an alicorn summons his wings from his back
• Nidra is simlar to Valiant except she has bat wings (naturally). No feathering or scales for her though
• Dove isn't a pegasus but her cape is meant to mimic the wings
