as many as possible. however, there should be 3-5 sentences in a paragraph.
A good paragraph should have one main thesis sentence. All sentences should pertain to that one thought. All sentences should be complete. The paragraph should convey one main point.
As many as you want. There is no law that says how many sentences make a paragraph. You should have more than one sentence in each paragraph, however. The general rule is: include enough sentences to make your point in each paragraph so that your essay is not confusing.
No rule but praxis. A page should be broken into a few paragraphs just to be easy to read. Look at a number of books , just open any one at random and see how many paragraphs you see. Each thought should be in a separate paragraph.
An average paragraph should have about 5-7 sentences in it! If you are writing an essay, I suggest you write more. For an essay I would suggest 7-10 sentences!
