Depends on the circuit and how it is used. Some cases, it if vital, some cases it is not. A good opamp, for example, will operate just fine if the supplies vary by volts, as long as the voltage stays above a certain minimum. SVRR...

...same thing. You would be better off using a voltage regulator or DC / DC converter, or for that matter just buy a 10V supply.

It can be done with the correct DC - DC converter. All you need is one with 25 volts output and an input rage fo 20 to 30 volts at the correct current rating. How? They have regulation via feedback.

Depends on the design. Usually there is a feedback loop of some sort to keep the output voltage constant. Otherwise it will vary with the input voltage and the load current.
