Not at the beginning of a sentence. As you know is a clausal sentence adverbial, and as such it should generally be set off by punctuation. That would mean a comma after it at the beginning of a sentence, a comma in front of it at the end of a sentence and commas on both ends when it appears in the middle of a sentence: "He is, as you know, rather obstinate."
It really depends on what the rest of the sentence is. For example, it is correct to say, "I don't know who will be there." In that case, there is no comma before "who". It is also correct to say, "My new neighbors, who have not spoken to me yet, keep letting their dog come into my yard and dig holes." That example does contain a comma before "who".
I don't know what you're talking about. Sorry...
There is a comma missing in the sentence. It should be written as follows, "Had I come to know about his difficulties, I would have certainly helped."
There is not rule that says you must use a comma before the word you exclusively. You would have to use a comma if the sentence would require one. Now if you were writing down the slang of 'you are' you would write it like this; you're. There must have been a sentence example for your homework assignment and your teacher wanted to know if you needed to use a comma in that sentence. Here is an example of the correct usage of the comma. I celebrate Easter, you don't, but I do every year.
When "however" does not begin a sentence, can have a comma or a semicolon before it, depending on how the sentence is constructed. If "however" introduces an independent clause (that is, one that can stand alone as a sentence), it should have a semicolon before it.Examples:Corrugated cardboard, however, should be put in the special cardboard-only recycling container.Clean corrugated cardboard should be recycled; however, greasy pizza boxes should be put in the trash.Let me know your decision, however you choose to proceed.

,I don't know maybe in the middle of a sentence

Before, i don't exactly know why that is. But that is how our complicated English language is.
It is almost always a comma, but rarely I have seen a colon. When you are writing a formal letter, it is a comma, but if you were to write a informal letter to a friend, it doesn't really matter. For all of the letters I write I use a comma, and so does everybody else I know.

From what I know, and its not much, Indians have always lived in America. They were here before us. They have always been here.

It depends on the context. Here are a few examples: "Charles! Shoes go on the floor! You know that, don't you?" And that, my friends, is how the story ends. Usually, if not always, a comma goes after 'that', in my experience.
No, they don't and I don't know if it's comma like coe-ma or comma like comma, and if it was a comma like comma, it would be an apostrophe.
