Newly set up campaigns always take time to reach your target customer group, you can set a low budget to review the effectiveness of each campaign. After a few days they do not bring good results, it is best to change your current campaign by setting up a new campaign.In the product testing period, you should take a look at all camps (good and bad) to see what did you do wrong.
Besides, when you want to stop the camp, just turn off the ad set since turning off the whole camp can lead to a few unwanted problems (limit dropped, unusual activity, get banned...).
Good luck!
What should i do when the camp is not showing good results? Like turn it off and set up
another campaign or duplicate it and change it?
