Question

Answer

Hi. If your question is about the tense used in the sentences, yes, they are correct. The Present Perfect shows and action that started in the past and it's still connected to the present moment.

Answer

All three sentences are fine.

The first two sentences are equivalent.

The only difference in meaning between the third sentence and the other two is that the third sentence specifies the gender of everyone.
