Is there a limit of number of questions in this forum?
No, but forum etiquette strongly suggests you keep a thread on any individual topic continuous (that means together no matter how long that thread might become). So, you should NOT post separate individual questions for every tiny nuance you might have.
The inherent nature of a forum is that thread topics get spread far apart as time goes by. If your inquiry is splattered into individual new posts, they WILL get scattered and your topic will no longer make any sense.
Anyone you hope to respond to you will lose all focus on the topic and will just no longer try to give you answers.
