Is it possible to run LHB Intercities with Non-AC Coaches safely at 200kmph (if we have upgraded tracks for 200kmph and a loco that hauls 24 coach train at 200kmph) without facing air drag and train being lifted?

The train won't be lifted. Technically, if you loco has the capability to haul that load at 200kmph and if the coaches are fit, then they can be run at 200kmph. But that's the the problem here. The problem is with the passengers.

At 200kmph, the effect of the wind is going to be very severe. A passenger sitting at the window with that wind constantly blowing on their face can sustain health issues. Having high speed wind slamming into your nostrils is not good.

The noise is going to be extreme. Even at 60-80kmph, the noise at the windows is very noticeable. At 200kmph, it will be enough to cause extreme discomfort.

Most importantly, the air drag is going to increase the power consumption of the locomotive. The energy costs will increase by a big amount compared to running the train at lower speeds.

So, can they run non-AC trains at 200 kmph? Probably.
Should they run non-AC trains at 200 kmph? No, they shouldn't.
