Thanks for your answer . But our main clarification is,  

1. Is it possible to change web role domain in azure?

2. Is it possible to configure IIS of web role hosted azure machine to do windows authentication?

1. No.

2. No.

If you want to host things joined to your corporate domain then it's going to have to be VMs. Or you delegate auth via ACS or ADFS and use Azure Web Sites.
