I've done the first one you asked about.
As to these:
2) Add Responsive Content Slider into col or container?
If you provide the actual content slider, I can always tell you how to add it to RFF. I don't make sliders that way, I have never come to terms with that programme. If, however, you are thinking of using the Orbit, that is no problem.
3) Add Responsive Forms created with WFB into col or container?
You need to provide the form, then I can explain how to insert it.
4) Add Responsive Menu into col or container?
I guess that is the menu which is one of the components. If you can't find out from studying the files Wayan and I sent you yesterday, I can explain it.
These things take time. I've been working for you over an hour right now. Don't expect me to sit here 24/7.
