How to listen to wi-fi broadcast?

Question

WiFi

So, I need to listen to the traffic that passes from the user to the access point (up to 10 users).
Question 1. Is it possible to do without connecting to an access point?
Question 2. How to use a sniffer (such as wireshark) to listen to all traffic passing through the router or intercept traffic (outgoing / incoming) from the host.
Condition for question 2: We will assume that access to the network has already been obtained.
I tried to listen to traffic with wireshark, but I'm having trouble, I only see what comes and goes from me. Then I tried to relay traffic from the host to myself using Cain & Abel software. And a new problem is born, I see everyone connected to the network, except for myself. Then I decide to make a tricky move, as I thought at first. Okay, since I can't see everyone, I'll take another machine and relay traffic through it, but that doesn't work!
Can someone explain to me what is wrong? Or suggest what software to use better?
ps wanted to use kali linux tools but can't connect to wifi network.
I don't know how you can listen to traffic using Aircrack-ng (I don't understand how it works)

Answer 1

Of course, you can listen, but it’s not like direct traffic, you still need to drive into it, and it’s not a fact that ...
... first, read about the composition and strategies for using Aircrack-ng, there are a lot of manuals for dummies for it
