Hope to see you there, I am also going on almost same days to almost same places.
1.I will use Faw v2 car with family. 2 males n 2 females. 2 kids of age 2 years n 6 months.What about road condition?
Roads are good to average with few bad patches here and there but generally good for cars.
2. Can my FAW V2 make this trip?
Any car with good tyres, breaks, clutch plate and good engine can make this journey. A lot depends upon driver's skills though.
3. After seeing my plan, Am i underestimaing time somewhere? Please help
me in finalising my plan as I have leaves till 2nd of July. On 3rd of
July I must have to go office.
Your plans seem over ambitious, you are planning of almost continuous travel to Hunza and you are the only driver. You plan to reach Naran in the morning at 8:00 AM and leave for Hunza at 9:00 AM. Where is the rest ? Don't you need rest ? My suggestion is to stay a night at Naran, have rest for few hours and then proceed to Hunza.
4. What will be the cost of hotels in Hunza, Shogran, Naran, Chilas, Gilgit? Like double bed room with 2 matrices?
Since this is my first time to Hunza, so I have no idea about hotel fares. It should be around Rs 4,000 - Rs 10,000 depending upon location, hotel condition, room type and facilities.
5. I have not booked any hotel as I never visited these places. So Will
it be ok to first reach there n then book my room after having some
bargain? Hotels will be available easily?
Looks like you are on suicidal mission 
You are strongly advised to book hotels now. If you don't, you are very likely to see trouble ahead, especially in these Eid vacations I have already booked PTDC even before the start of Ramzan.
6. What about traffic jams as It will be Eid vacation?
Since it is vacation time and start of the summer season, you should expect bad traffic jams at various places like Abbotabad, Mansehra and Naran. If you must go on the evening of Eid, my suggestion is to take Muzaffarabad ---> Garhi Habibullah----> Balakot route. Don't go via Abbotabad on Eid day evening.
7. Can I make this trip with my family keeping in mind of children as well please?
Sure you can, but please book hotels now.
8. Which one is better to visit in this time frame. Hunza or Skardu or Fairy Meadows? Im not good in tracking.
Hunza area only because road to Skardu is not in good shape, it will take at least 6-8 hours to reach Skardu from Hunza. Also don't go to Fairy Meadows with toddlers.
9. Please mention over all budget as well of fuel, toll tax, meals etc categorically?
I am going with my 02 kids and wife. I have estimated it to be around 150K at least for me. I am also visiting Deosai, Rama, Fairy Meadows, Khunjrab, Naltar etc.
10. Any other places to visit other than I mentioned?
You don't have much time but Naltar Valley would be a nice place to visit.
11. I will be the only driver in this trip, Will that be hectic to drive for so long?
This is usually hectic and risky as well. God forbid, if you just catch fever ???? Have good rest and don't eat unusual food. I will also be driving throughout this trip but my wife is a very good driver (this will cover any risks or emergencies).
