Radio-isotope halos and Diamond Crystal studies aren't negative. Creationists went looking specifically looking for "clocks" that would measure through different means than radiometric decay.
The magnetic flips, wasn't negative. The Creationist specifically theorized and predicted that lava cooling would have captured the record of quick magnetic flips.
The vestigal organs can be stated as a positive. That all human organs would serve important functions.
The missing links is a negative, but it's a pretty damning negative for evolution.
"Non-coding DNA having function" is a positive.
But it's not true. De we really need to show the skull pictures again? And again, the magnetic flips are prediction of basic ferromagnetism, not of creationism. (Also, the radioisotope halo and diamond crystal studies, assuming you're talking about what I think you are, are bogus because they don't account for secondary decay products.)
Still waiting for a specific prediction, of creationism that shows what we will find and where we will find it.
Here's another fulfilled prediction of evolutionary science:
"It was predicted that humans must have an intermaxillary bone, since other mammals do. The adult human skull consists of bones that have fused together, so you can't tell one way or the other in an adult. An examination of human embryonic development showed that an intermaxillary bone is one of the things that fuses to become your upper jaw."
