I don't know what Google is expecting, but if I were interviewing you those sort of answers would satisfy me, if you explained your situaiton and made a decent attempt to provide some useful answer. e.g. for #2 they're not actually doing due diligence on your current employer, they want to know about the sort of environment you thrive in, so talk about what you're looking for in a company's culture. As you said, #3 is a chance to give lots of real world examples and play to your strengths. For #4 they don't need to actually know about that specific project, they just want to know how you handle projects, so if there's a way you can answer that from your own experiences then that's fine. I'd say your #5 is fair enough too. At that point that's probably the sort of thing you'd want to turn around. e.g. ask if they have hired people who have come from self-employed backgrounds, and if so how did they handle it.
