Is this product safe for repairing fiberglass fish pond?

I would use it if it was me. It's for repairing fiberglass boat hulls, it has been used for cracked engine blocks,etc... Yes, I would It's good stuff.

I'm looking to attach wire hanging hardware (a metal hook) to the back of a 20lb aluminum sheet to hang it on a wall. Is this the right product?

I have never used it on aluminum but I wouldn't hesitate to try it because it is so strong when cured. I have NEVER been disappointed in this product over 10 years.

can it be painted? Wanting to use it on a porcelean sink prior to resurfacing/ repainting the sink.

it can be sanded and painted~!have to give it proper set up time~!

Will this work on a plastic pipe manifold

If the plastic is a hard plastic like PVC it should work. If it is a slick plastic like polyethylene, it likely will not.
