4. What does conciliatory means in this story?

Conciliatory is used in Chapter Four.

"Joe, who had ventured into the kitchen after me as the dust—pan had retired before us, drew the back of his hand across his nose with a conciliatory air when Mrs. Joe darted a look at him, and, when her eyes were withdrawn, secretly crossed his two forefingers, and exhibited them to me, as our token that Mrs. Joe was in a cross temper."

In this context, conciliatory would be defined as "peacemaking."
