The iCloud is block and we can’t reach it in every way possible.

There is nothing you can do, the phone is useless, since your friend can't provide the information needed to remove the activation lock How to remove Activation Lock - Apple Support

Activation Lock for iPhone and iPad - Apple Support

f you use security questions with your Apple ID, or if you don't have access to a trusted device or phone number, go to iforgot.apple.com. Then you can unlock your account with your existing password or reset your password. What if I can't access a trusted device or didn't receive a verification code
