My pond is empty right now for repairs, and the lily pads are visible. The roots are very hard to pull out. Is there something safe to kill the pad? If I clip off the lily at the base, will it regrow?

A clip is a section of video or audio from a film or audio track whereas a media file is an overall description of any item that comes under the...

Yes, but you need to prepare the substrate before fiberglassing the pond. It can be done by sanding the surface and washing the surface beforehand.

You need to break up the tubers and replant them 1 m (40") apart. If you don't do this, it won't produce many artichokes.

Only if you need them out of the pond for one reason or another. If you are okay with them in your pond, let them be.

You should probably get a refund from wherever you bought that. With a smell like that, I would assume the coffee is not safe to drink.

On most occasions no, but if you don't follow all steps, it may have the chance of regrowing.
