That's pushing it but it can work. It depends if you have central A/C, electric range, water heater, etc. Those are your amp suckers. You'll need to be mindful when operating the hot tub; not running the dryer, oven, or other large appliances.
Yes, but the 60A breaker will trip when your house box reaches 60A draw. I would not recommend it.
Yes, use a 60 amp breaker to go to the 60 amp sub panel.
the circuit breaker spark when it comes an over load, loss contact,but the probable cause is loss contact...and also the circuit breaker is going to be damage or destroyed.
Depends on the size of the wire going to the A/C. If the wire is AWG #10 you cannot install a 40 amp breaker. If the wire is AWG #8 you can.
Safety First! 1) Remove all load devices from the breaker circuit (unplug everything). 2) Reset breaker and observe. No problem, move to step three. 3) Add back one load device at the time. If it's winter, and the device that reproduces the problem happens to be a space heater, stop here, you solved the problem. Move the space heater to a less populated circuit. 4) If you add your I-Pod charger and the breaker trips, you could still need an licensed professional to investigate. In my experience (almost 39 years) doing electrical work, circuit overload is the most common cause.
Well the most probable answer is that you are exceeding your electrical load limits. This means that all the circuits on that 100amp breaker, i.e. ligts, outlets,etc are drawing more than the 100 amps you have available. You can most likely fix this by installing a higher amp main breaker, however if you do that you also need to check and possible install larger circuit breakers. Also you might want to check all your grounding and make sure you actually have all your outlets and lighting going to "earth ground", and if you have any GFCI circuits which would be in the bathroom or the kitchen and they are tripping due to excess amp draw or a short, this also could be a possiblilty.
If it was two wires under one screw on a single-pole breaker, that would not be proper, and most probably against electrical code.If it was two wires, each under their own screw on a double-pole breaker, then that would be a 220 volt circuit; each wire going to its own "leg" of the breaker panel.
Its not recommended because your new main breaker will allow up to 100 amps and your old wire can only safely handle 60amps. If you put a 60amp main breaker in the new box, that would be acceptable. No, it is perfectly safe. Because the box is overrated, there is no problem. If the box is the main panel, and not a subpanel, install a 60A main breaker so you cannot overload your service. If it is a subpanel this 60A breaker should be in the main panel.
It depends on what else you are running in the house. Add up your amperage to see if it is more than the 125amp rating. Which should be below 105 amps constant to keep from overheating the main breaker. If you are not running a big central ac system or a electric oven and water heater you should have no problem running the hot tub.

Overload or short in system
The sump pump breaker alarm will keep going off if it is being overloading. This is usually a result of a failing pump or a clogged filter.

IMO it would be because the circuit breaker has the possibility of going bad and not working (allowing a short to move through the device), but fuses blow (cause a break) no matter what if shorted.

the amount of power going to the object will will cause the circut breaker to blow. if the object is not connected to a breaker then the object will catch on fire.
On a star delta starter a motor overload or a motor going to ground and cause a short circuit will cause the overload protection to trip. These overloads have to be reset before the motor can be restarted.

Blown fuse or tripped breaker. Replace the fuse or reset the breaker.
