No, you don't need to learn all java packages and classes for the OCA and/or OCP exams.
In order to give you some (good) advice, you'll need to decide first which exam you want to take. You provided the link to the API of Java 6. Is this because you want to take the OCPJP6 exam? Or do you want to get certified for Java 7 or 8 (and then you need to take OCAJP7 or OCAJP8 first)? Which exam you want to take, depends on what's important to you (e.g. money, available resources,...). In this thread you'll find an overview of all possible paths (OCPJP6, OCAJP7+OCPJP7 or OCAJP8+OCPJP8) you could take to become an OCPJP certified Java programmer. And this thread also contains some valuable information about which OCA version to choose. So I would advice to read these threads and let us know which certification exam you want to take so we can answer your other questions.
I am planning for OCAJP 7 exam. I am a beginner in java and know almost all concepts of core java(but not in depth). Right now I am learning java from here. I am planning to take this exam in mid of September 2015. Can you please guide me how can I make it possible. and how much time should I devote to study . I have bought oca/ocp book by Kathy sierra too.

To pass the OCAJP7 exam you need an in depth knowledge of Java and OO basics. The Oracle tutorials are a very good (free) starting point. The K&B7 study guide is currently probably the best study guide on the market (to prepare for both OCA7 and OCP7 exams). You asked for free mock exams, in the OcajpFaq you'll find an overview of all free and commercial mock exams.
I would advice purchasing the Enthuware mock exams. It's very cheap (only 10 USD) and offers excellent value for money. I would suggest using the self test questions and mock exams in K&B7 to study and prepare for the OCA7 exam and use the Enthuware mock exams to monitor your current level and verify if you are ready to take the exam. Because your mock exam score is only useful if you have taken the mock exam for the 1st time (on a 2nd or 3rd attempt your score will not be a good representation anymore of your current level/knowledge).

That's always hard to tell, because it's very personal. Some people learn new concepts very quickly, others need more time. With so many quality hours of studying it should definitely be possible. And if you finished studying all the OCA content, you can take an Enthuware mock exam and verify your current level and knowledge. And you'll know your weaker areas (e.g. inheritance, overloading,...) or maybe you run out of time and you need to improve test-taking skills
