Let’s go through each sentence one by one and change it from active to passive voice.
In passive voice, the object of the active sentence becomes the subject. We also use a form of “be” + past participle of the verb. The original subject (if mentioned) comes after “by”.

→ Portuguese is spoken in Brazil (by people).
*(We often leave out “by people” because it’s obvious or not important.)*

3.
The cleaner has cleaned the office.

*(Again, “by somebody” can be left out.)*
