Sirius actively supported James, leading to Snape bestowing an equal and life-long grudge upon Sirius. Sirius later claimed Snape was "this little oddball who was up to his eyes in the Dark Arts", from Snape's first moments at Hogwarts. He was one of the many people who hated Snape.
Snape and Lily were best friends at Hogwarts, but they met before that. As shown in Harry Potter and the Deathly Hallows Part 2, the two were originally neighbors, with Snape hailing from the wrong side of the tracks.
No, he didn't know. That's why Rowling specified that in Vold War One the Death Eaters were organised into cells, with each only knowing the identity of a few of the others. So Snape didn't know Pettigrew was a Death Eater, and he didn't know that Sirius wasn't one.
No, James and Sirius did not apologize to Snape for their bullying, but that doesn't mean they never felt regretful of their actions. They had seven years of mutual antagonism, and they loathed each other to the bitter end.
Snape seems to shift his loyalty between Dumbledore and Voldemort throughout the Harry Potter movies. Only the last film reveals that Snape had always been on the good side. He swore to protect Harry and did Dumbledore's bidding in his war against Voldemort, including infiltrating the Death Eaters.

Was Snape a good guy or bad guy?
In an interview, Rowling described Snape's character as an "antihero". She has said that she drew inspiration for Snape's character from a disliked teacher from her own childhood, and described Snape as a horrible teacher, saying the "worst, shabbiest thing you can do" as a teacher is to bully students.
McGonagall later learned that Snape was secretly Harry's protector and had killed Dumbledore at Dumbledore's request. McGonagall then made a controversial decision to add Snape's portrait in the Headmaster's Office as a testament to his bravery.
There is always an implicit ire directed at James the most, because as we see in SWM and as Snape's dialogue pretty much everywhere implies, he was the one who lead the bullying. Although he hates Sirius and Lupin quite a bit too.
Lily didn't agree to date until after Snape had already ruined any chances with Lily by calling her a mudblood and made it clear that his sympathies lay with the death eaters.
Even though Snape repeatedly tried to apologize for his mistake afterward, it became clear that it was yet another incident that had done irreparable damage to their friendship.
Did Remus Lupin know Sirius Black was innocent throughout The Prisoner of Azkaban? No. He suspected Sirius until the end of the year, when he spotted Peter on the Marauder's Map.
The Harry Potter and the Prisoner of Azkaban book showed that Sirius Black had been believed to be the one who betrayed James since the members of the Order of the Phoenix thought him to have been the Secret Keeper for the Fidelius Charm placed on the Potters' cottage in Godric's Hallow.
After all, Severus Snape was a proud man. Sirius Black was also a proud man. He was also assumed guilty and Dumbledore had no reason to assume differently, and no reason to help him as Sirius hadn't repented, showed remorse, or asked for any help from any Order members.
She missed Snape, but she knew she could never forgive him. Snape never stopped trying to make amends. But Lily remained steadfast. She could not, would not, forgive him.
J.K. Rowling apparently confirmed that Lily Potter was pregnant again when Voldemort murdered her | Fandom. Thus, in murdering the Potters, save for Harry, Voldemort also killed a younger brother or sister that Harry would ultimately never know before it was even born.
One with a severe dislike of Lily's former best friend. Let's get into your points one by one, though I would like to say first that I'm not sure if that quote from Lily about James making her sick really matches up with her being the 'submissive one'. - Yes, Lily knows James is a bully. That is why she loathed him.
Yes, he did bully Snape but so did the other marauders like Sirius - Remus wasn't really any better - did he stop James from bullying Snape? Did Peter? And yet people still call Remus a good man (which I believe fully :)) But James Potter died to protect his family. He gave Sirius a home when he needed it.
Why does James Potter call Snape "Snivellus" at first if he knows that Snape is from an old wizarding family? We don't actually know whether it's James or Sirius who first gives Snape the “Snivellus” nickname.
Snape was influenced by peer pressure and humiliation. When he first called Lily a m*dbl**d, James Potter was teasing him. Snape, afraid of what kind of shame he would bring to his parents and house, called Lily a m*dbl**d.
The once shy and awkward Neville Longbottom showed his true bravery during the battle of Hogwarts and eventually became the head of Gryffindor House while also teaching new students Herbology, his favorite subject.
At this point, McGonagall begins to gain the upper hand as it becomes clear he cannot further transfigure or counter her attack, so the only way he avoids it is by taking refuge behind a suit of armour that he forces in front of him.
