Convert this sentence into plural form

I got a question wrong, with more than one fault:

Nous nous sommes brossé les cheveux was given as the correct answer, but isn't "brossés" the correct form of the past participle in this sentence?

Please could you explain why prochain is placed in front of 'concert', when it is normally placed after nouns?

Why can’t I say “Je le trouve grossier/irrespectueux?” As the sentence read “I find it disrespectful?”

Je pense que j'entends "Je prendrai un avion..." au lieu de "Je prendrai l'avion...".  Qu'est-ce vous entendez  ?

Je ne suis pas sûr qu'il ________. I'm not sure he's coming.(

To say in/during the afternoon, we use "dans"? (ex. Il y aura un vent frais dans l'après-midi). To say in/during the morning or evening, we don't use a preposition, correct? (ex. Je vais au marché le matin/ce matin).

Je vais aller à l'épicerie. - this was marked wrong because the answer should be without aller, but is it grammartically wrong or just not what the answer asking for?

Why not on est resté

or nous sommes restés

« On » is singular, grammatically speaking, like the impersonal/formal « one » in English, but in the example it appears to be being treated as plural «  nous »

I would have thought On est restés was incorrect.

Hi, in “Curieuse de nature, je m'y étais aventurée !”, is “curieuse” in its feminine form (as opposed to the masculine “curieux”) because the speaker is female? Am I right in thinking that this is not influenced at all by the female word “nature”?
