Yes, but very rarely, if the sentence is short, you don't actually need it!
Not necessarily. Only use a comma when the final please is a request. For example, we say Do as you please; but Sit down, please.
No. After the word and comma can not be used, as it is grammatically inappropriate to use comma after conjunctions such as and, which are called coordinate conjunctions.
A comma is typically not needed after the word "please" in a sentence unless it is part of a direct address. For example: "Please, pass the salt." In most cases, such as "Can you please help me," a comma is not required after "please."

Yes, the word "please" should generally be followed by a comma when it is used at the beginning of a sentence or clause. For example, "Please, send me the report." However, if "please" is placed at the end of a sentence, no comma is needed, such as in "Could you send me the report, please?" The usage can depend on the specific context and style preferences.
In many cases, the word 'however' is followed by a comma. The problem with the word is that one must be careful not to over use a comma. However the word is used,(note that there is no comma used in this connection) the word itself frequently does not need a comma as an automatic punctuation.However, (meaning 'on the other hand') phrasing will most often determine if the word is followed by a comma. These two instances here are examples of when to use or not use the comma as punctuation for this word. When the word is used as a substitute for the phrase 'on the other hand', it is most often followed by a comma.
