You may or may not have a leak but the sunken area is caused by the collapse of the sand or ground under that area of the pool allowing the liner to fill in the hole created by that collapse.

Very small drillbit underneath taillight. small hole water drains out. I recommend sealin the hole with silicone after.
That hole is called a "weep hole". When the water pump goes bad, water will leak out of it. If you plug it, you won't know when the pump goes bad.
Need to know the diameter of the hole.
Yes you can!
You can't ... since the above ground pool is made of vinyl material, you need to apply a vinyl patch. Has to be a like material to be compatible.
