Answer:
Flipendo - this spell knocks objects over and stuns magical creatures. He learns this spell in his first ever Defense Against the Dark Arts class (DADA)

Wingardium Leviosa - levitates small objects. Harry learns this in his Charms class.
Incendio - shrinks spiky bushes and stuns Venemous Tentaculas. Harry learns this in Herbology.

Verdimillius - cast on invisible things to make them appear.
Locomotor Mortis - spell used to immobilize enemies.
Mucus Adnauseam - poisons the enemy with a serious cold. Makes spell use harder for the person hit.
