Would it work on gluing back rubber pads on the nose bridge of plastic frame sunglasses?

Yes, This glue will be effective in gluing pads onto sunglasses frames. If they are metal, you'd be best off scuffing the metal with sandpaper to ensure adhesion; for plastic this won't be a problem.

do you need to use a primer?, can I use it fix my cracked kicking fin for swimming (silicone/rubber), need to be a strong bond

No. I used it on my tennis shoes. I just cleaned the area with alcohol.
