Yes you can. The critical thing is that amps match. All 250 volts says is that it will work up to that value. You wouldn't, for example, use a 20 amp fuse since that could allow higher currents than the microwave could handle. The fuse blows because of excessive current.
Yes. It should be a 'heavy-duty' extension cord, rated for 15A or 20A .
Yes, a 250V fuse can replace a 125V fuse if they have the same ampacity rating. The voltage rating is simply the maximum voltage that the fuse is capable of safely interrupting. You can go higher, but you can not go lower. Obviously, the form factor of the fuse must be the same, but that is often the case.
no.. it could damage your electrical components.
The voltage rating of a fuse (in this case 125V or 230V) defines the maximum circuit voltage that the fuse is safe to be used on. A fuse with a voltage rating of 125V should not be used in a circuit with a voltage greater than 125V. If a 125V fuse were installed in a 230V circuit and an overload current occurred, the fuse could explode.
Yes, fuses of a higher voltage can be used safely. What is not recommended is to use a lower voltage fuse on higher voltages.
No it will not work.
It depends on what you are powering with the circuit, but probably not. The 1.5 amp fuse would blow in normal operation of the device.
no
Yes

No, the voltage rating should not be exceeded. However, you could use a 250v 10a fuse for a 125v 10a fuse.
No, it cannot.
