All bullets are powered by Dust. Dust is the propellant. This was revealed to us in the first chapter of the manga, which is one of the ones that we know are definitely canon to the show. Therefore, by copying Coco's bullets she is also copying the Dust that acts as the propellant, and she can copy the effects of dust.

Apply the same thing to the other weapons she copies.

And...how else would her weapon generate hardlight but by a computer? Seriously, there needs to be some sort of program that can look at the weapons from the pictures she takes, generate a 3D model that is then translated into a hardlight copy which is created outside the box.

Her semblance only allows her to copy the movements of the owners of the weapons. The weapon (camera, box, and computer inside the box which generates the hardlight copies) is what copies the dust functions. She doesn't have to have the camera to copy a persons moves - she can use Nora's hammerstrike without a copy of Magnhild if she wanted to, she just built the weapon to compliment her semblance. It was even stated in the Director's Commentary when they talked about her semblance that it was the best matched weapon and semblance so far in the show.
