Notice that the text is in the past tense.
Notice that there are two “different” tenses: The past simple and the past perfect.
When do we use Past perfect ?
The past perfect tense, therefore, is used when we want to speak about two actions in the past: one happening first and the second later. The second action should always be in the past simple. AND THE ONE THAT HAPPENED BEFORE IT IS IN THE PAST PERFECT (PROGRESSIVE).
In brief, We use the past perfect for an action which happened before another action or before a certain time in the past.
Past Perfect Form :
Subject + Had + Verb in the past participle.

In these last examples (5 and 6) we have the past perfect continuous because the verbs used are progressive ones: “to fight” and “to wait”.
