In general, you shouldn't put multiple questions into one post. Simply post multiple questions.

If one of your questions simply is an extension of another question (like when you want a general answer instead of one specific to a single software/OS) then you can edit the other answer and put a bounty on it to draw attention to this.

If an existing question is extended to cover more ground than it previously did, this is always a welcome improvement.
