Yes you can do that as long as it will fit in the fuseholder. It is acceptable to replace a lower Voltage Rated fuse with a higher but NEVER replace a higher with a lower. There are several things to consider when replacing a fuse: 1) The minimum voltage rating of the fuse is equal to or higher than the voltage of the circuit you are placing it in 2) The Amperage rating of the fuse does not exceed the capacity of the circuit you are trying to protect. Always replace a fuse with one that has the same amperage rating. 3) The interrupting rating of the fuse is sufficent for the capacity of the circuit supplying the fuse. If replacing a fuse always use one with an interrupting capacity equal to or greater than the fuse you are replacing.
I think you are confused. I can't imagine any kitchen appliance with a 125 Amp fuse or breaker. If you replace and fuse with a lower rated fuse it will likely just blow. You always need to replace with the fuse designed for the appliance.
There are many different reasons why one may choose to replace a fuse with a fuse of another voltage. If you do not have another 125 volt use, you can substitute a 250 volt fuse in many cases.
No
Assuming the wiring is sized for 12 amps, you can replace your fuse with any 12 amp fuse or smaller and with a voltage rating at or above what you expect to connect to it. The amp rating protects the wire, so you cannot go above what the wire can handle. The voltage rating is the max voltage that it can safely protect, so you cannot use a fuse with a lower voltage rating than you expect to connect to.
a 6.3 amp 125 volt fuse a 6.3 amp 250 volt or 300 volt is fine with similar time delays depending on application it may be easier to find a 10A it should still protect most of the components
I think in most applications the difference between 6.3 amps and 7 amps is meaningless. However, if your equipment calls for 6.3 amp protection, 7 amps may allow your equipment to burn up before the fuse blows.
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
Yes. The cord only transmits the power. Whatever that goes in is what comes out.

You need to define what you mean by 2.0 and 1.6.

Yes, you can substitute a 250 volt fuse in place of a 125 volt fuse. You just can't go the other way around. As far as 1.5 amperes in place of 3 amperes, well, you've got a problem there because the fuse will blow at about 1.5 amperes instead of 3 amperes, so the intended load will not be met. All of this, of course, assumes that the physical size of the fuse is the same. Bottom line is never substitute fuses.
You physically can but sit will be unsafe, and will not protect the circuit because it will not blow when it should. Only replace a fuse with the same size fuse.
Yes, the voltage listed on the bulb is the nominal voltage and it will work perfectly on a 120 volt circuit.
The replacement fuse must be of the same amperage as the one it is replacing. The voltage does not come into play in this application.

NO! There are 50 bulbs in a 2.5 volt string or 125 volts. There are 35 bulbs in a 3.5 volt string or 122.5 volts. If you put 50 3.5 volt bulbs in you will have 175 volts and most american house have 110 volt service so you will have dim bulbs.
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
Yes, that is safe.
You tell yourself the 125 volt receptacle is a 120 volt receptacle. They're the same thing.
