Question is not clear; however, if you were to install a 120watt bulb into 90 watt rated socket then it may work for a while for some.
yet, even if it works then after a while will start burning quite often and the fixtures itself will be damaged permanently
As long as the lamp holder will take the larger wattage lamp and the current of the circuit is sized to take the larger current then yes, the lamps should be interchangeable.
If the socket threads of the lamp are the same then yes the bulbs can be interchanged. The 5 watt bulb will glow brighter than the 4 watt bulb. If by a 4 watt light you mean a 4 watt fixture, then it is not recommended to place a larger wattage lamp in a fixture that is rated by the manufacturer at a specific operating wattage
Yes. The rating of bulb fixtures is there to discourage people from using bulbs that create too much heat. Obviously, a 75 watt bulb will produce less heat than a 150 watt bulb so it's quite safe to use the smaller bulb. If you overheat a lighting fixture you can cause premature failure and possibly even a fire.
A standard 1157 bulb has a 5 to 8 watt dim element and about a 21 watt bright element. An aftermarket 1157 LED bulb is between 3 an 5 watts total.
A desk lamp which takes a regular size bulb. You could easily change it to a higher watt.
40 watt light bulb

The light bulb needs to match the ballast in the fixture.

The voltage isn't decided by the lamp, but by the supply the lamp is hooked up to.

Of course
A desk lamp which takes a regular size bulb. You could easily change it to a higher watt.
If the exit fixture uses a LED lamp it will have a 1 to 3 watt rating. If it is a incandescent bulb, each lamp will draw about 25 watts each.
Because it takes more current and power and produces more light power. Running a 100 w lamp costs 4 times more than a 25 w lamp.
Usually the 60-watt limit is used to prevent the lampshade overheating, so a 75-watt bulb should not be used. But if more brightness is required, try a low-energy bulb because a 15-watt one gives the same light as a 75-watt incandescent (old-style) bulb. Or a 20-watt would be even brighter.
