I'm not sure who Anjali and Jai are in this love story. They might be characters in a local story, or they could be real people. If it's a fictional story, the author would have created their personalities and backstories. But without more info, it's impossible to say exactly who they are.
Paula, in the '600 lb life paula's story', is an individual whose journey is the focus. She is presumably a person who has been struggling with a weight of around 600 lbs. Her story might involve her emotional state regarding her weight, her relationships that have been affected by it, and her fight to get healthier. It could also show how she copes with the physical limitations and the social stigma associated with being severely overweight.
There is not enough information to precisely say who Bani and Jai Walia are. They might be characters in a local drama, a family - centered story, or perhaps they are names from a particular cultural or sub - cultural narrative. Without further details, it's impossible to define them accurately.
It depends on how you define 'true'. Some parts might be based on real events or inspired by them, but it likely has fictional elements added for dramatic effect.
It can be considered a real story to some extent. Maybe it takes inspiration from actual incidents and then adds some fictional elements for dramatic effect.
I'm sorry, but I don't have specific information about 'Jai Rao' without more context. It could be a name of a person not widely known, or perhaps it's a specific name within a particular community, family or a story that is very niche.
