Can a 20-amp breaker for an outdoor hot tub easily be changed to a 50-amp breaker for a larger hot tub and what does this involve?

There are several factors in trying to make do. A 50 amp service requires larger wire. While a 20 amp service typically requires AWG #12 wire the 50 Amp would require AWG #6. In other words, you would end up replacing wire and breaker. I would refer you to www.spadepot.com for typical requirements from the spa manufacturers and information that is needed for installation per NEC code. I am not an electrician, however, I installed a 50 Amp breaker 240V (double pole) at my main breaker panel and ran enough wire to reach site. I used AWG #6/3 with ground and has worked fine for 16 years. Another thing you must consider is how far you will be from the main breaker. NEC (National Electric Code) probably will state that at runs of over 50 foot you must upsize the wire to #4 due to voltage drop that will cause amperage to increase.

What to do with gaps in breaker panel?
That's why breaker panels are provided with knock-out blanks. You only remove the blanks that you need. If you have removed too many of the blanks, install unused breakers in the empty spaces. <><><> Your local hardware store sells breaker knockout blanks or plugs so you do not have to install unused breakers. They are simply plastic spacers that snap into your breaker cover (called a dead front) to keep energized parts from being too easily available for contact. -- Sparkfighter

Do circuit breakers trip more easily in humid weather?
Ambient temperature has an effect on the tripping point of a breaker. If a breaker is operating at near capacity the additional ambient temperature will lower the breaker trip set point. As to humidity making the breaker trip easier, the answer is no. Humidity makes the ambient temperature seem hotter that the true temperature is. A standard operating temperature of breakers is from from -5 to 40 degrees C. If the breaker is used at higher temperatures than 40 degree C they have to be de rated, 50 degrees C to 90% and 60 degrees C to 70%. The standard humidity rating of a breaker is 85%. Humidity that is constantly higher than 85% will require a special tropical environment type of breaker that extends the humidity range up to 95%.
Is it safe to trip a breaker by touching the hot wire to the ground wire if you cannot identify the correct breaker?
This is one way that can locate hidden circuit breakers. It is not the best way because an arc flash could result if the breaker does not trip. An arc flash can generate enough heat instantaneously to burn the flesh off of any exposed skin. If there is combustible products or combustible air mixture that is in the general location of the arc, a fire could be easily started. The way that I do it is to load the circuit. I have a 3000 watt heater that I plug in to the circuit that I am trying to locate the breaker for. This loads the 15 amp circuit to 25 amps. The circuit breaker is located in a few seconds.
Are elec main breaker boxes predetermined on how many 15amp and 20amp breakers you can install in the number of slots?
No. If you look at your current main panel and look at the size of the mail breaker you might have 200A or so. Then if you add up all the breaker amperage ratings you will likely exceed the main breaker value. This is because the design of the various circuits takes into account the normal load on each circuit and expects that duty factors of each circuit will not be constantly at the maximum values. If you had a clamp-on amp meter you could easily determine how each of the current breakers was loaded under various circumstances.
