Can I still change Site Title after it got indexed by Google

What you did is just normal for every site owner, it should be fine. Resubmit sitemap on GWT whenever you do changes or set up new pages.

As per my seo experience. You can sure change title of your site. You will check this update in search engine after once again crawling. It may take some time but you can. But do not frequently change the title as it may effect on your ranking.

you can change the titles, description, keywords according to the SEO requirements. nothing will happen.

You don't need to worry about that you can change the title any time. There is not any bad effect.

Yeah, its right you change the title and then see after crawling it would be there in Google search. but if you change your URL then you need to again re-indexed that page because keep URL in its Google Bot through that it recognize the page.
