How to renew a domain name which is expiring soon

What is the starting date of the renewed domain?

How long does it take to renew? I just renew an expired domain (within 1 month), but not seeing its website back (on a wordpress platform hosted on Bluehost).

Hello, if I'm transferring a domain from a different host to NameCheap, the money I'm paying is for domain renewal or for transfer service?
