Hallo there

this site https://www.airdroid.com/parent-control/how-to-track-phone-using-imei-online/ & imei-tracker.com explains how to track a mobile phone by IMEI from what I read and searched know I'm still having trouble and struggling understanding about this. Here is my question

1. Can this site imei-tracker.com site do this?
2. Can anyone track IMEI with a third party website or IMEI tracker service?
3. Tracking the phone number and IMEI is same method?
4. Can IMEI be changed? How?
5. How to track my lost phone without using IMEI and phone number?
