Need help with current zoho mail setup

Dear Support,

Hope you are doing good,
I am Amit handling this admin account of zoho mail account for domain simpli-logic.com with registered user id #60015184236, currently on Free plan and with 4 users. 
While migrating on to zoho mail, seems my tech did a mistake and added group alias emails as in user/ person email. I want re-create these user/ person email into group alias and forward the emails to the actual person email boxes. And, I am aware that group alias emails doesn't hold any mailbox, and I am fine with it post transfer of existing emails. I have tried searching for the exact solution but couldn't find it anywhere on the help section.

Appreciate if you can help me out with the way that I can use to get it done.
Thanks.

B/R,
Amit V.
