Any help on how to make people the brainliest ?​

If two people answer a question,then an option come,"mark as brainliest",tap that and the answer which you like more will be marked as brainliest. Only mark an answer as brainliest when it helps you more than the other answer.

After they've done answering, you can see a tab mentioning "Mark As Brainliest". Select it and your done.

hope it helps
