How to raise a shy child and manage Social Anxiety

Hi, my son is of 5 years and he is as reserved as his father. He never talks to to new person or makes friends of his own. Every time I have to force him to make friends. How can I change his nature.

My 8 year old is very confident at home otherwise. But as soon as she goes out or guests visit us , I see a different side of hers. She would just go to a separate room , try not to be noticed and not greet anyone or talk with even children. It takes her quite a long time to adjust in the presence of guests . How can this be dealt with?

My 3 year old would just not mingle with agemates whenever taken to a park or a party. He would keep on clinging to me. I have tried making him comfortable till he adjusts but all my efforts go in vain. Due to this I am also not able to enjoy any party or even going out. what can be done so that he gets comfortable with agemates and not cling to me?

Hello doctor,My daughter aged 5yrs does not mix too much with new people and specially kids(gets scared of children who are little loud in behaviour) this lockdown also affects her social behaviour and She has too much separation anxiety. please suggest
