This is my first time doing board level repair and I’m not sure if I can attach the charger port on after I tinned the pads. Someone please help. Im attaching pictures for any help.

Several pads are partially missing. You’ll need to check the continuity between those pads and their connection points to insure you have a complete connection. If everything checks out okay, then you can solder the flex. You’ll need to use a lower temperature than normal when you solder a flex otherwise you can damage it.
