Hi @Eng,
Hi @nilesp,
You can deposit your Approvers in SharePoint list according to you need, and add a column named Response to mark to status of approver response.
If you build your approval process as follows, it might simplify your approval process.
Step1: Get items of the Approver List.
Step2: Create action Start and wait for an approval (V2), and append the ApproverEmail.
-If the approver response the approve request, update the item set the Response as Yes.

Step3: Since your approvers number are 6, and they're approved at the same time. you could set the action of Apply to each by click the Settings, and set the Concurrency Control as On, and turn up the Degree of Parallelism to 6. So that ,the 6 approve requests could send at the same time.

I hope it can help you. If you still have questions, please contact us.
