The terminology about "chorus" gets most at first.

"Verse" and "Chorus" terminology refers to lyrics.

Song terminology, the Chorus is one iteration of Verse plus the following Chorus.

Both are called the Chorus.

Then repeat that as many times as necessary to get the job done. Use the second box with numbers in it that appears to the right of the songtitle window. Default is 32 bars, simply click there and click where you want the end of your chorus (that combination of one "verse plus chorus") and that part's done.

For the 4 bar ending, you would likely invoke a TAG ending of two bars using the Song Settings dialog (Rightclick at the bar and choose Song Settings). Choose two bars only because the default in BIAB is a two bar ending anyway, the two bar TAG plus two bar ending should make up a 4 bar ending for you.
