Their relationship could be more hesitant. Since they are starting anew, they might not immediately recognize the bond they had in their past lives. It could be a slow process of rediscovery.
Hinata might be shocked at first. She has always adored Naruto, and this sudden act of aggression from him would leave her stunned and unable to process it immediately.
Hinata would be overjoyed. She has loved Naruto for a long time, so his proposal would be like a dream come true for her. She might start crying tears of happiness and immediately say yes without hesitation.
Hinata might be very hurt. She's a sensitive person, so Naruto yelling at her could make her feel small and sad. She might start to doubt herself and her abilities.
Hinata could use her Byakugan to find weaknesses in Sasuke's defenses. Maybe she spots a chakra - based trap that she can manipulate to create a distraction and then make her escape. She could also use her Gentle Fist techniques in a creative way, like redirecting Sasuke's attacks back at him to create an opening for her to run.
At first, Hinata's reaction might be one of shock and disbelief. She has probably never expected Sasuke to do such a thing. However, she is a strong - willed character deep down. So, she might start to plan her escape. She could use her knowledge of the ninja world and her own family's techniques. She might also try to find out if Sasuke has any allies or if there are other forces at work. She could try to turn the situation around and make Sasuke realize that what he is doing is wrong by appealing to his better nature or by using her own skills to outwit him.
It's hard to give an exact number. Different story arcs and battles led to the deaths of multiple hashira. Some died heroically, while others met their fate in unexpected ways. The count changes as the manga progresses.
Another way is to join fanfiction communities or forums dedicated to Naruto. Ask the members for recommendations. They can point you to some great stories that don't involve any forced relationships. Some members might even have their own collections of fanfictions that they can share with you, which are often carefully curated and free of inappropriate content.
