Answer 1

Can you upload the psd. people are already compiling and throwing off the finished project for you. And, of course, free of charge.
Maybe read some theory. Practice yourself. And for layout issues, contact Google, video tutorials ... Since you are planning to do layout, it may be better to spend more time studying. Because if you get ready-made pieces of code here, it will not be a finished project, but a collection of bicycles, which in the future will be impossible to maintain.

Answer 2

give z-index to the active window, turn off the rest

Answer 3

do hiding all before showing the selected one (styles, as I understand it, are implemented)
