What is the age of the baby?if 6 months or above offer water and breastfeed frequently to avoid dehydration.u can offer juices as well buttermilk etc.

Absolutely normal.. exclusive breastfed babies can go without passing stools for days. Just check if baby is comfortable and not in pain it's fine

At this age formula should have been weaned.u can go for cows milk or even include more dairy products like cheese,paneer,curd,buttermilk,butter etc.

Consult ur Dr....

Give him tender coconut, juices in the day time

It's too early. Wait till 6 months. And it's very normal too be constipated when you introduce solids. She will be fine in a day or two. Give her water and milk properly. Include fiber diet like pear prunes papaya in her diet whenever you introduce solids. And consistency shouldn't be very thick in the beginning.
