Can it repair a basket ball sized hole in a brick wall ?

It would not work for a vertical wall unless you use it to stick something like bricks together. It is too thin to support itself in a quantity large enough to fill a basketball size hole.

Is this waterproof and can be used to repair fountains? Im afraid water will soften it.

I’m sure it’s waterproof. I have it holding up my driveway wall

Does this dry hard like concrete? I need to patch a 1 1/2 inch hole in a concrete block wall around an exterior faucet.

Yes, it does. I used it to patch up my exterior brick when I had to replace my outside water spigot.

Would this be good for repairing cracked or broken fiber cement roofing shingles--would it serve as adhesive to hold the shingles to roofing felt?

I would not use this to repair fiber cement roofing shingles. I do not know if or how well it would stick to roofing felt.
