I'm going to answer my own question.
I have found the NodeBB Featured Threads plugin.
With this one I can stack the posts I like to show.
How to generate a static page ? In home I want to implement about page and contact page with form.In footer I want to include a link with term of conditions. How to do this?
You might want to look into this plugin: https://community.nodebb.org/topic/142/nodebb-plugin-static-page-static-pages#1235 & you can edit the footer content from the Widgets area in ACP + you can use Bootstrap 3 markup when creating new tab links etc.
