If it is newly sprayed it should not be a problem.
No as long as the cement had gone of originally this is not a problem.
I believe the contractor should be responsible for repairs if the cracks are due to faulty workmanship such as improper soil compaction or application of gunite in cold weather etc. If the cracks were caused by a force of nature such as a flood this should be covered by homeowners insurance. In closure what was the warranty on the pool. Most reputable gunite applicators provide a warranty on the pool shell.
you can either use a good epoxy pool paint if you intend refurbishing the whole pool or use an epoxy paste. V out the cracks and fill with epoxy paste.
drain the entire pool follow the cracks. find a sealant. (check with your pool company!) apply sealant. let dry for the time suggested. If you wish to find a waterproof paint and paint it the same color of your pool.
It is not normal for hairline cracks to form in the plaster pool finish in the first few days after application and water fill. However, it does happen and one of the most common reasons is because the pool was filled too slowly. It is important to fill the pool as quickly as possible to prevent this from happening.
"lighting" can not cause cracks
If the cracks are in the surface layer of the fiberglass, the problem can be rectified. These "spider" cracks form in the gel coating of the fiberglass, due to pressures that can occur from a pool that was not installed quite level, for instance. These types of cracks aren't structural. If the bubbles are raised, I would call a pool repair service.

Yes. Suggest you inspect pool and drain closely for cracks or other damage.
Don't know if there is such an animal. Do you mean fiberglass? Once a pool shell is installed it can be tiles completely.
