If you haven't defined a "playlist" yet for the five YouTube segments, you can do that. (When you play each video, look for links under it with the label "Add To..." or "Playlists".)
(1) First, you need to make your playlist visible. On the main page for your account, above the "screen" is a button for "Videos and Playlists". Click that to open up some options about displaying your playlists (and which playlist to present on your account page.)
(2) After you've set that, you should see the playlist in the right column on your main page.
And above the screen there should be links for "All"/"Uploads"/"Favorites"/"Playlists". Click on "Playlists" to see the links to your (one) playlist.
