Hi Gagan it is all normal while teething, you can gently massage her gums with ice cold cloth. You can also give her cold teether, hard boil the carrot sticks, freeze and offer. All this will help her.

Smashing her head to wall ...and pull her ears ..I think she is having pain

Why do you need calcium tablets? There’s no need of any tablets for babies. 2 teeth is pretty good at 9 months. What’s that worrying you?
