As long as you declare everything you bought overseas and/or cannot produce evidence they were purchased in India, you won't have a problem. Note, however, you will probably owe import duty & taxes for those items you take home that didn't originate there.
For an example of what you may expect to pay, you could try this calculation page.
Also note that putting some of the items in your checked in luggage does not obviate you of the requirement to declare.
EDIT: Per jpatokal's comment, the calculator I've linked here is for commercial entities and he found a more useful one for individual travelers.
