Hello how to reset all of plugin data ?
It mean, I want to remove all settings, social login datas, etc.
And I'll re-install.
You can use the "Reset All Options" button to reset the wpDiscuz option. You can use the "Remove Vote Data". To remove the social login data you'll need to do manipulations with DB.
Yes! I want to remove social login data. How to delete that's database?
It's hard to detect the users that were being logged in via social login. You'll need to check in wp_usermeta table and find the users by met_key, then delete the user in wp_users table.

Please don't touch the DB if you're not familiar with it.
