My phone has been hacked and I've reset my AppleID but it is still happening. Do you have any other recommendations?

Random texts and emails are not signs of being hacked. You are just being spammed, which happens with public information.

Your phone was not hacked. Your Facebook and other app accounts are not related to your physical device.

You need to learn how to keep accounts secure. Look for/take local programs that teach people the basics of going online securely, recognizing and preventing falling for phishing and, etc.

Your phone has not been hacked; it is not possible to hack an iPhone unless the hacker has physical possession of the phone and also knows the phone’s passcode and your Apple ID and password.

My situation is same as my partner’ phone has reset all password but few moment later when we try to log in and is show the password isn’t correct. And his most of app have been deleted. Now he can’t even log off iCloud. What can we do to get it back or to find out who did this to us please

That sounds like your gmail account was hacked, not your iPhone.
