You'll just have to :
1. Create your shipping zones via "Hikashop->System->Configuration" :
Sure you can also use the 'Maharashtra' State, you won't have to create a shipping zone for that state, but regarding the other states of India, you'll have to create a shipping zone.
2. Configure your shipping methods via "Hikashop->System->Shipping methods->'YourShippingMethod'" :
You'll be able to use the "Zone" option via the "Restriction" tab of your shipping configuration page (You'll just have to click on the "Restriction" check-box).
