How do I know which certificates I can delete and which ones I have to keep?

Good evening,

I'm having problems with TestFlight that around 3 weeks ago started returning errors to me and all my testers saying that "the requested app isn't available or it doesn't exist". I'm trying to find a solution, and I was checking my profiles. I noticed I have so many, and some duplicates. How do I know which certificates I can delete and which ones I have to keep?

Most signing identities are disposable. You can delete them and then re-create them afresh and nobody notices. There are exceptions to that rule, however, and the screen shot you posted references one of them. Developer ID signing identities are precious, as discuss this thread.
