Yes, you should use a comma to set off a direct address in a sentence. For example, in the sentence "John, can you please pass the salt?" the comma after "John" sets off the direct address.
A comma is not necessary after "as well as" if it is being used to introduce more items in a list. However, if the phrase "as well as" is used to provide additional information in a sentence, a comma may be needed before and after it to set off that phrase.
Not always: the word "which" requires a comma when used as an indefinite pronoun, in contrast to the incorrect use that was originally in this post: "sentences which require a comma before the word "which" are far less frequent" (not only is that incorrect - that use of the word would take a comma as well - it is an unverifiable assertion). That sentence should have taken the definite "that", as in, "sentences that require..."" In speech, the difference is usually expressed by a difference in intonation. In writing, a restrictiverelative clause is not set off by commas, and that is the preferred subject or object of the clause, although many writers use which and who or whom for such clauses. A nonrestrictive clause is set off within commas, and which, who, or whom, not that, is the relative pronoun to use as the subject or object of the verb of the clause."
You use a comma in a sentence to separate items in a list, to set off introductory phrases or clauses, to separate independent clauses when joined by a coordinating conjunction, and to set off non-essential information such as appositives or parenthetical elements.
Yes, it most deffinetly does. When you combine two sentences you should always use a comma, unless the sentence already has many commas in it. In which case you get ride of the conjunction and use a semicolon(;).
The main rule of a comma is to use it to separate the elements in a series of three or more things. You should also use a comma to set off quoted elements and to separate coordinate adjectives.
No of course not!only when you have run on sentences.

In general, you do not use a comma after "and". One situation in which you would use a comma after "and" is where the "and" is followed by a phrase set off by commas:"Symptoms can include headache, fever, nausea, and, in rare cases, paralysis."It is much more common to use a comma before "and", or to use no comma at all, either before or after "and":"I will set up the equipment and organize the materials, and you will give the first presentation. ""I walked around the pond and saw some turtles, an Eastern Cottontail rabbit, and a Great Blue Heron."
Not necessarily. There is no word or phrase in English that requires a comma before or after it. Whether to use a comma is entirely a matter of sentence structure.
No, typically you do not use a comma after the word "oh" if it is being used at the beginning of a sentence. If "oh" is being used in the middle of a sentence to express surprise or emotion, it is usually set off with commas.
Commas are used to separate items in a list of three or more items, before a coordinating conjunction, and to set off introductory material.
