There is text "build and upgrade before 15th day" so we cant upgrade them after that day ????

Yes you can upgrade them after. They will just disappear from the store after that time

Great question. You can upgrade as many multiple buildings as you have bonuses. So if you have a +1 building upgrade and buy the construction worker, you can upgrade 3 buildings at once (1 normally + construction worker + your temp bonus)

Keep in mind that constructing a new building isn't taken into consideration with this bonus. So you could have 1 new building being constructed and then all of your other buildings being upgraded. :)
