Will this happen automatically? Or do I need to change a setting.
They will appear automatically - https://xenforo.com/community/recent-activity/

Also, can profile posts and comments appear in the new posts feed?
If you mean the block on the forum index, that is for posts only.
There is a separate block for profile posts, which can be enabled/disabled in the Node & Forum List options.

There are also separate tabs on the new posts page for both.
