Is there any way to moderate posts first? After a moderator or admin approves then only it will be visible. And if it can be done for specific group then even better.

You can set custom permissions for a specific user group in the settings of the user group (Users & Groups > Groups > Select your group > Forums and Posts > Search for Moderation Options). You can also set custom permissions for a specific user group in forum/category permissions (Forums & Posts > Select your forum > Permissions).

I have tried those settings. I have created some fake new accounts and posted. But when I log in through any moderator username nothing is there in the 'Awaiting Moderation' section.
