Need help to creating a Process Builder

Hi Team,
Can any one please help me to create a ProcessBuilder for below request.
1.If Is this approved Field(Picklist) = "Blank means None" , Request (Textfield) = "Empty(No value)" then Approval Status(Picklist) should be NotSubmitted.
2.If Is this approved Field, Request field = "RC-01234" then Approval Status should be Submitted for Approval.
3.If Is this approved Field = "Yes" , Request field = "RC-01235" then Approval Status should be Approved.
4.If Is this approved Field = "Yes" , Request field = "Empty" then Approval Status should be Not Submitted.
5.If Is this approved Field = "No" , Request field = "RC-01236" then Approval Status should be Rejected.
6.If Is this approved Field = "No" , Request field = "Empty" then Approval Status should be Not Submitted.

Let say If i select "IsthisApproved" = Yes, Request = some data (RC-01234) then Approval Status should be Approved. so hear we are updating the Approval Status field based on the IsthisApproved and Request fields.similorly other points as well. Please help us on this

Thanks in advance
