1. AC Voltage stabilizer? 2. UPS? 3. Inverters for domestic use? Answered

1.  In my area where I live we have power (electricity) facilities but the voltage always fluctuating and we have to attach expensive VOLTAGE STABILIZERS to each and every electric/electronic items for to avoid damages.
I am expecting some valuable ideas to make cheap and best  voltage stabilizers / UPS / Inverters.
Is it possible that I can connect one unit (VS) to multiple gadgets.

Thanks in advance

Where I live we have the same trouble as well as constant blackouts I hooked a battery charger to a 12 volt battery and then an Inverter. I attach a 12 volt solar cell during blackouts and I use this only on things that can be damaged during a power surge and on what I want during a blackout.
If you would like to check out my Modified Sine Wave Signal Generator, it might be just what you are looking for if you are thinking of building your own.

The multiple gadgets'  total maximum power demand must be less than the maximum power the VS can supply,  If it is, plugging them all in at once is fine. (Note that motors may draw extra power when starting up.)

Valuable ideas: None, except that you've described one viable approach: Convert to DC, put that through an inverter to convert back to (more stable) AC. You'll lose some power in the process, of course.

Reminder: If you're driving electronics, you probably want to make sure you use a full-sine-wave inverter -- or at most, modified-sine-wave -- rather than square-wave.

An off-the-shelf UPS box may or may not be sufficient for your needs. Check its specs. I know folks who have used them to get around problems with wonky power, but I couldn't tell you which ones.
