How much time do people spend with friends

How much time do people spend with friends My question is A. Can you recommend me a crash course in friend groups and B. How much time do you or people spend with friends. It just occurred to me that I might be lonely. I do have someone and I’m in touch with friends sometimes. I see people on hours long calls and painting or watching movies with friends and I am filled with jealousy. I have people who I thought of as friends but only ever saw a few times and never spent much time with. Feel free to comment anything remotely related. Younger/teenager as you would have guessed.
