Hi,
The first image shows you your HOST table, this is associated users that are NOT authenticated.
The second image shows you your ACTIVE table, this shows authenticated users.
So you have 6 people connected to your system but only 2 are logged in and using the system.
I recommend you go on the MTCNA 
they are using my internet or its mean my hostspot is hacked can you tell me what i can do and what is the
MTCNA…
That does not show your router has been hacked. If your hotspot was set up correctly, they are just connected to the hotspot interface. If they have not authenticated, they can’t access the internet.
