iPhone 6 will not accept my Apple ID in activation lock

So i tried factory resetting my iPhone to restart its data, but after I set it up it showed up a screen that shows an activation lock, so I decided to type in what it looks like to be the one of the 3 iCloud’s that I have that start with m and ends with @gmail.com. But two out of the three keep saying they cannot be used, looking more deep with research I’ve found on Reddit that u can remove the phone from the account on the devices using the Apple ID, when I did that nothing happened, and when I tried to type in the emails and Apple ids it didn’t work? Does anyone know how to fix this or have any experience?
