If the staging environment is an isolated environment for testing by testers and also sandbox is an isolated environment for testing, So what are those differences? Actually I could not find any useful and clear information on.

Good question. Given the background you provide they appear the same. This is true in that they are both isolated from the production environments. They should not contain production data. etc. However there are a number of differences particularly in how they are used.
- Staging environment
A good staging environment will be a close replica (less the data) of the production system. It is used to test upgrades and patches prior to going to production. This means that it should be a controlled environment where the engineers responsible for the production deployment are allowed to test the rollout instructions.
Access restrictions in a staging environment should be as close to production as possible. I.E. deployment by those engineers who are responsible for deployment. No root (or privileged access for developers).
- Sandbox environment
As the name suggests this typically a playground for the engineering team. It has less restrictions than a staging environment because it is designed to allow the engineers to try out things easily and quickly. A sandbox environment is likely to drift away from the production environment as engineers try out different versions of the product, dependancies, plugins etc.
Access to a sandbox environment typically allows privileged access to any engineer (developer, QA etc.) who are working on the project for easy / quick deployment and debugging.
