The man was Walter Cunningham senior, but he was with the whole Cunningham clan with hopes of lynching Tom Robinson.
Scout had courage when she was visiting Atticus late at night and witnessed the mob coming to (presumptively) hurt his client. She talked to the angry men and distracted them, ultimately calming them down.
As for the jail: Atticus went to the jailhouse to protect Tom Robinson from the mob he knew was coming for him. Although he was alone against several men, Atticus held his ground until his children showed up. Only then did Atticus seem truly afraid because they were in danger. He'd expected to get roughed up a little in the struggle to protect Tom Robinson, but he never imagined that his children would be in the way. That's when his courage failed him, but Scout's complete innocence saved them all.
In Harper Lee's novel, To Kill a Mockingbird Jem tells Scout that he fears, their father, Atticus will get in trouble. Jem fears this because he thinks the group of men were apart of a mob that was upset about Atticus helping Tom Robinson.
Jem showed signs of growing up and identifying with the adult world when he protected Scout during the attack by Bob Ewell, demonstrated maturity by understanding Atticus's defense of Tom Robinson, and when he confronted Atticus about the trial outcome and racism in Maycomb. These instances highlight Jem's evolving understanding of justice, morality, and the complexities of the adult world.
chapter 10 Atticus was feeble: he was nearly fifty. When Jem and I asked him why he was so old, he said he got started late, which we felt reflected upon his abilities and manliness. He was much older than the parents of our school contemporaries, and there was nothing Jem or I could say about him when our classmates said, "My father--"

Jem didn't do anything, he just brought scout to the jail while the mob was there. Scout showed the mob that Atticus helps everyone. The mob wanted Tom Robinson, but they would have to go through Atticus (hurting him in the process most likely) to get to Tom. If Jem didn't bring Scout, Atticus would have been injured in some way.
Its Alexandra, Alexandra showed compassion, and she understands everything that Atticus does now for the first time =D
In To Kill a Mockingbird, the crisis where Atticus shoots a rabid dog demonstrates to his children, Scout and Jem, his exceptional marksmanship skills. These skills surprise the children, as Atticus's shooting ability was previously unknown to them.
"Somehow, Atticus had hit her hard in a way that was not clear to me, but it gave him no pleasure to do so. He sat with his head down, and I never saw anybody glare at anyone with the hatred Mayella showed when she left the stand and walked by Atticus's table." To Kill A Mockingbird (Pg. 188)Scout notices that Mayella glared intensely at Atticus (like she never had seen before) as she leaves her stand and walks by Atticus's table because Atticus treated her politely, and she thought he was mocking her because of this, but mainly because he asked her so many questions that proved her story wrong.
Even though people criticize Atticus for being a "nigger-lover" and they don't say it to his face, he doesn't treat them any differently he would normally would. He treats them with respect like he would treat any other human being. For example, Jem gets upset that Miss Maudie calls Atticus a "nigger-lover", Atticus hears this but still treats Miss Maudie in a civil way like a gentlemen.
Scout and Jem were disappointed in Atticus because they initially felt that he was not as physically skilled as other fathers in their community. They wanted him to be like the other fathers who participated in physical activities and showed off their skills. However, they later learned to appreciate Atticus for his moral integrity and wisdom.
