Can twitch mods give vip to people?
No, only the broadcaster can add the user role of vip to others on their channels. If you want to vip someone in your own channel you can simply use the chat command as follows.
Type: /vip [username]
You can also do this in the roles manager section in the dashboard. To get to the roles manager follow these simple steps! 
- Go to the creator dashboard
- Click on the community section to expand it
- Then click on the "Roles Manager" option
- Press the Add New button, type the username of the account you want to add for vip and then press the + button to add the vip role.
You can also see how many vip slots you have unlocked when in the roles manager and by clicking on adding in a new vip user role. See the above screenshot for a example of that occurance.
How do you get vip slots on twitch?
Streamers can get 10 VIP slots by completing the "Build a Community" achievement which is gain 50 followers and 5 unique chatters during a stream session. This will scale up as you have more unique chatters during your streaming.
