Concrete, as well as many epoxy mixes will harden underwater. Someone needs to be IN the water to properly apply the patch material.

Use a good quality cement and push the cement in as far as you can, if it a thru-hole, do the same on the inside, smooth one or both patches flush. If its below ground level apply a "Tar base material" to the patch after the cement dries, this will help in waterproofing the patch.
You can patch a hole in your Halloween decoration by heavy duct tape (ensure that you can't see it) or you can try plugging the hole with a piece of vinyl with fabric glue.
Yes, if you know where the hole is. WalMart has a patch kit for underwater repair. Last year they were $5.95 - 4"x4" patch, cement, instructions. I am sure pool shops offer this too if you feel better about buying products there.
I guess the answer really depends on how big and deep the hole is. Cracks, holes and tiles can be repaired using all purpose waterproof cement. I have used a product by Leslies Swimming Pool Suplies called "Patch It". Not only does Patch It easily patch the hole, it can be applied underwater without having to drain the pool. Good luck!

If the hole is clear of the concrete get a little bit of pipe 25mm or an inch and cut it along the length so that you have a ring that opens up. Get some PVC primer and PVC solvent cement . use the primer to clean the outside of the pipe with the hole in it and the inside of the patch. put solvent cement on the pipe around where the patch is going. stretch the ring so it opens up and covers the hole and hold it in place. you can do this with a suitable hose clamp. wait a couple of hours before use. if you can reach the inside of the pipe you can use a similar procedure,
Cementing a well is either pumping cement into the drilled hole to decomission or plug up the hole, or to pump cement in between the casing (pipe) and the hole itself. This allows control of pressurized oil leaking from the hole.

Yes, pool companies sell "Under Water Cement" and patch kits. If you hole is bigger than the usual patch, ask the pool company to sell you a piece of used liner.
Yes, but the walls of the hole may contaminate the cement. Mixing the cement may be very hard, and precarious. Further, you may not be able to remove all the cement from the hold afterwards. It is more advisable to use a cement-mixer.
