Yes they can kill shrimp. Maybe even small fish if they're big enough.

Most mayfly nyphs feed on diatoms and aglae. They do not get very large at all.

No, the larvae wont reproduce, only the adults. They can change the color of their carapace slightly to mimic their surroundings. Fish love to eat them

HAHA, seeing as I ID'ed the insect larvae incorrectly, jkan is correct...

This is actually a Damsel Fly larvae, in which case it is predatory.

Sorry for the confusion everyone, I should know better

I would remove it, as Im sure it will develop a taste for shrimp.
