I think that:

Osana- Borrowed money from someone who claimed to be her friend, then threatened to harm her if she didnt pay him back

How to befriend- Threaten the one who gave money, or kidnap someone close to him

Amai- Laces the food she eats with drugs (Not the stuff she feeds other people)

How to befriend- Help her get over her addiction, since her family is becoming suspicious of her behaviour

Kizana- Her grades have started dropping and her parents are abusing her, because they expect perfection from her

How to befriend- Steal an answer sheet for the upcoming test (like you would use to expel Kokona), and let Kizana photograph it, then she can use the answers to get a great score on the next test (Could also be used to expel Kizana)

Oka- (TW) She self harms, but not out of a mental disorder, but because she believes it will help summon a demon, she wears sleeves to hide scars but pretends its because they're cute

How to befriend- I couldn't think of anything for her, honestly

Asu- She is being forced to take drugs to advance her sports skills, even when she doesnt want to

How to befriend- Threaten the person who is making her take drugs with blackmail

Muja- Accidentally sliced someone's arm with a needle during nursing school, and is being sued with no evidence to support her.

How to befriend- Get Info-Chan to look through Muja's experience at training school, and get every detail (in Muja's favour) of the situation

Mida- Accused of R**ing a student at the last school she visited, and is in an ongoing case from which she could be sent to jail

How to befriend- Similarly to Muja, find evidence against the claims of R*pe

Osoro- Accidentally murdered someone she thought was trying to threaten her, but nobody has found out yet

How to befriend- (If this becomes a feature) Send Osoro the postcards your mother sends you with tips on how to get away with murder, and stay somewhat safe

Hanako- She got pregnant from an exchange student at her old school, however since he went back to his country she has nobody to raise the child with her. She doesnt want Taro getting a girlfriend so he will be there to support her and the baby, since she doesnt have any money to support it

How to befriend- You would help her build up the courage to tell Taro, then (If the small town is implemented), you and Hanako would go round and do jobs and earn money to buy baby items for her

Megami- She hates men in a sense, because Saisho Saikou, her grandfather, forced his son (CEO) to put Megami through extreme training. The CEO didnt want to do this, because he had awful memories of the training he was put through, at a much faster rate than his sister, however Saisho threatened to kick him out of the family like he did to his daughter if he didnt, leaving him no choice, even though he regrets the decision every day

How to befriend Megami- After you do a task for her, and the members of the student council, she will let her guard down around you slightly, so you can ask her to follow you, and you can take her around school and let her talk to all the boys who are nice, so she will see that she doesnt need to hate every single man, and she doesnt need to fear them, like she would fear her extremely strict and scary grandfather
