This question is difficult to answer, because I believe you are unsure of what a compound sentence is. A compound sentence has two complete clauses that are linked together by a comma. In a compound sentence, you could replace the comma with a period and not change the meaning.
Example: John ate his lunch outside, Sally ate her lunch in the cafeteria.
If you are linking two separate clauses with a conjuction, the comma would go before the conjunction to avoid creating a run-on sentence.
Example: John ate his lunch outside, and Sally ate her lunch in the cafeteria.
Yes, in most cases, you should use a comma before the conjunction "and" in a compound sentence to separate the two independent clauses. This helps clarify the different elements of the sentence for the reader.
No, you do not always need to put a comma after the word "so" if it is the first word in a sentence. It depends on the context and flow of the sentence.
You can put a comma before or after just about any word if the sentence structure requires it. If the sentence structure does not require it, it may be permissable to use a comma to assist in clarity and avoid confusion. Otherwise, don't use a comma. Have I confused you yet? Using a comma does not depend on the word, it depends on the structure of the sentence.
No, there is no need to put a comma behind the word "that" in this context. The use of a comma depends on the structure and flow of the sentence.
Yes, typically a comma is used after a transition word or phrase at the beginning of a sentence to separate it from the rest of the sentence for clarity.
Yes, a comma is usually placed before the word "or" when joining two independent clauses in a sentence. This is known as the serial comma or Oxford comma.
Nope.
No.

A compound sentence ir normally separated by the word "and" or "because", and a comma. If you can break the sentence in to 2 different parts and they are both complete sentences (meaning they both have a subject and an action) then it is a compound sentence. To put it more simply, a compound sentence is 2 complete sentences combined in to one whole sentence, separated by a comma.
If it is used as a conjuction in a compound sentence, it comes before the word. Ex: We need to stop at the store, which is on our way to school.
