I understand that in usergrid UI I can create an Individual collection , but it does not allow me to create a collection under a collection. Is there a way of doing that . Otherwise we will be forced to write business logic in the proxy layer which we don't want to do.

There is no concept of subcollection, but you can use connections. So you can do something like this:
POST cats/fluffy/hasa/toys/ball
The above would mean that that an entity of type "cat" is connected to an entity of type "toy" that is called "ball" by a connection verb "hasa".
You can also store sub-objects in an individual entity (e.g. full JSON is supported). If you want to describe your use-case a bit more, I can maybe recommend other ways to structure your data.
