Question: What exactly was happening when Harry casted red sparks with his wand in the maze? All things just seemed to get more aggressive. Did Dumbledore say to Harry that he can use red sparks if he want to give up?

Answer: Harry was not giving up. Harry saw that Fleur needed help, and cast red sparks to bring attention to her.

Chosen answer: In the book, the finalists were told to shoot off sparks out of their wands if they got lost or got into trouble in the maze - sort of a distress flare. As to why things get nasty at that moment, most likely it's because Mad Eye has rigged the maze to make sure that Harry wins and touches the cup first, which wouldn't happen if Harry had to give up.
