How can I edit BuddyPress pages

Hello, Thanks for all your past awesome support. I really appreciate all of the work you guys (and gals) put in making the themes and plugins, and all the support you provide.

I have been having fun learning how to work with the upront platfom with the spirit child theme. I am having a problem with editing the BuddyPress pages (adding widgets, images etc. to activity, profile, etc.) for my site. Can you tell me if this is possible and if so, how can i achieve it. Thank you again for your awesome support
