What is the difference between copyright infringment, and intellectual property violation? What is the difference between copyright infringment and intellectual property violation?
Copyright infringement is just one of several ways to violate a person's intellectual property rights. Others include patent infringement, trademark infringement, and misappropriation of trade secrets.
What happened is that you created a legal mess. You are obviously on the hook for copyright infringement. The maintainers of the project will scramble to replace your code with newly written code. They will likely ask your company which code they are complaining about - that puts your company into the problematic situation that they shouldn't identify code that isn't theirs, that it will be hard to sue for infringing code when they didn't give the project maintainers a chance to fix it, and that everything they identify will be replaced. Since it is your actions that caused the trouble, anyone suffering damages from your actions can sue you.
The GPL does not explicitly specify a time within which the source code must be provided, which probably means a &quot;reasonable time&quot; is allowed. What is &quot;reasonable&quot; would eventually be evaluated by a court, if the matter ever got that far. But please note that only the copyright holder (or the holder's authorized agent) can sue for infringement. The license does not give other people a right to sue for infringement, and I doubt that any license could grant such a right. One could inform the copyright holder who could sue, but the holder need not sue, and undertaking such a suit would involve expense, time, and effort. Whether the offer to provide the source constitutes a binding agreement is not clear, and may well vary in different jurisdictions. The question does not state any particular jurisdiction.
When you license your IP (like a song) you can specify the terms and conditions of its use by the licensee, including revenue shares from any derived work. However, if, as your comment suggests, you grant an "informal" license, and later decide that you want to "firm things up" with a license having different terms, that's a matter you would have to either negotiate or litigate with your counterparty. If you want a common reference point for negotiation of this sort of license, you might have a look at compulsory license terms.
Almost none. It is a legacy of the era when copyright protection was a function of year of publication. Including it is appropriate, however, to meet the formal requirements for a legal notice of claim of copyright which has some procedural implications if it is omitted.
"There is a free mp3 app from a friend who asked me to publish it in my account, which I didnt check properly." You violated Google's policies by uploading an App that you did not have full control over and/or was not developed by you. As well, the App possibly violated Google's policies in terms of violating licensing for code libraries that were included, had code included in the App that was malicious or violated privacy, or was otherwise not compliant with Google's terms. Google's policies are legal contracts which you agree to when you open an account. You reserve the right to end the contract by deleting your account. They reserve the right to end the contract when their policies are not followed. See https://play.google.com/about/developer-content-policy/ "This sudden termination comes as a shock and Google's decision seem very rude to me." You may think it is rude, but Google is fully within its rights to terminate your account because you violated their terms. It matters little that you did not get the previous warning emails from Google; you are responsible for monitoring the account email for policy updates. If you’ve reviewed the policy and feel this termination may have been in error, please reach out to our policy support team. Try that; you might attempt to explain that it was honest error on your side.

The copyright holder has the rights in whatever he created. If you have created something new based on his idea, the law will generally not be interested; but if your expression is recognisably a copy with a few changes, he can prevent publication or demand royalties. If you are uncertain which side of the line you fall, you should ask a lawyer (or, more cheaply, write to the author and ask if he objects).
