Can I make friends by staying in a B&B in Hangzhou?

It depends on what kind of friends you want to make. If you just want to make friends who also like traveling, I think you should choose a youth hostel. But if you want to make friends with local people, actually stay in a hostel. B&Bs are also pretty good. For example, last time I booked a B&B in an old residential area through Mu Bird B&B. The middle-aged and young people there were very familiar with each other. There is still a local from Hangzhou. In my chat list, it mainly depends on whether you dare to take the initiative to speak.
