Hi... do I have to have all the dragons for the next event to fight with nyx? Or if I only get the positivity dragon I can fight using him and other dragons of mine or obligatory have to use all the summer dragons and positivity dragon for the next event? I need to know if someone can reply, thanks

First, please do not put your entire question in your title in the future. Second, yes you will need the summer dragons for the dragon rescue. It has both said if High Positivity is required but I am assuming he will be.
