Shakespeare did not write about writing plays; he just wrote plays. I'm sure the phrase "Life Plots" never escaped his lips. He knew that life was like a play sometimes; it was a favourite metaphor of his. He knew that there were comedies and tragedies, because they studied that in school, but he was happy to mess with the conventions which distinguished them, as were some of his contemporaries.
He didn't. Shakespeare never talked about his life.
When people say Shakespeare they mean William Shakespeare the playwright. There was only ever one of him.
Apart from the obvious ones like Robin Hood or Superman or Elizabeth Bennett, who Shakespeare didn't even write about, almost all of Shakespeare's characters appear in some way in the sources he took his plots from. Shakespeare modified and tweaked their characters by making changes to the plot and by giving them self-revealing lines to say. It may be going too far to say he "created" them if by that you mean he invented them from whole cloth.
Shakespeare would say "Wherefore art though?"

Shakespeare's language was English. "And" in English is "and".
he was a famous man long ago and had many wise words to say
There is no tangible evidence to say what Shakespeare's favorite character was.
Hath.
Shakespeare spoke English, you would say 'our'.
For the most productive part of his life, Shakespeare was his own boss, or rather was one of his own bosses. The theatre company and the Globe theatre were owned by a partnership or "sharers", all of whom had a say in how the business was run.
Too many to count. And they are so common, we do not notice. Do you say "Ah, that's Shakespeare!" every time you hear the word "assassination"? Probably not.
