Explanation:
In German, nouns (person, place, or thing) are capitalized. (Just so you know which word is the translated verb and noun.)
In German, 'man' means one in terms of you (e.g. 'one should look both ways before crossing the road'). The verb 'darf' means to be allowed and its combination with 'nicht', or not, signals that something isn't allowed.
1. 'Musik machen' means to play music.
2. 'Fussball spielen' means to play soccer/football.
3. 'Schreien' means to yell. (But you could also use 'sprechen' or speak because the sign could be interpreted as such.)
4. 'Rollschuh laufen' means to rollerskate.
5. 'Rad fahren' means to ride a bike.
6. 'Essen' means to eat. (Or if you want to be more specific, you could say 'Eiscreme essen' to mean to eat ice cream.)
7. 'Singen' means to sing.
