b.2 bonding pairs, 4 lone pairs
c.3 bonding pairs, 2 lone pairs
d.5 bonding pairs, 1 lone pair

To determine the number of electron pairs with both lone and shared, you should draw out the Lewis structure for each molecule. When you see electrons that aren't paired, you should take them in account for lone pairs, while electrons that are paired through bonding should be accounted for.
