The first one : a teacher wants two of her students to not talk and to be quit
the second one : a mother wants his son/her daughter to tidy her room because it's messy
the third one : a father wants his son to not be rude anymore and to be kind

A) Le professeur demande aux élèves d'arrêter de discuter, de se calmer ( quiet!= du calme!)
b) La mère demande à sa fille de ranger (to tidy up) sa chambre
c) Le père demande à son fils d'être poli (don't be rude = ne sois pas grossier)

hope it helps
scuse je l'ai fait en français au lieu de le faire en anglais : The teacher ask his students to stop talking and be quiet; the mother ask her daughter to tidy up her room, the father ask his son to be polite
