The purpose of the Lease Obtained is to give you a "Temporary" IP Address that will change when the lease Expired date comes close. EX: (Lease Obtained: Sunday October 18, 2012 at 12:30:15 PM / Lease Expires: Friday November 12, 2012 at 10:45:55 AM) "The client starts to renew a lease when half of the lease time has passed. For example, for a 24 hour lease, the client will attempt to renew the lease after 12 hours. The client requests the renewal by sending a DHCPREQUEST message to the server. The renewal request contains the current IP address and configuration information of the client."
8 days Above answer is not exactly correct. The default period of time (T1) is 1/2 the time of the original DHCP lease time. So if you have a lease time of 2 days then the first attempt to renew the lease will be in 1 day.
DHCPACK is a confirmation for the acceptance of the DHCPOFFER from the Client. DHCP Server Sends DHCPACK in response to DHCPREQUEST to renew the lease time or to confirm the allocated IP address.

Yes. The client will renew the same address lease for as long as the DHCP server allows.
DHCP will request a refresh at the half-life of the lease time. So, in your case, 12 * 60 mins, or 720 minutes.
renewal time value-after 50 percent of the lease time is expired the DHCP client attempts to renew its lease with the DHCP server that issued the IP address. This renewal time value is referred to as T1 Binding time is value- after 87.5 percent of the lease time has expired the DHCP client attempts to renew it's lease again if unsuccessful, it initiates a DHCPDiscover broadcast request to receive an IP address frt om any DHCP server on its network. this Binding time value is referred to as T 2
Unless the offer to renew was made in writing and signed by the landlord, he may legally withdraw a verbal offer at any time.
Absolutely.
Yes, you can certainly renew a car lease. However, it really depends on the leasing agent. For example, Honda does allow for renewed car leases.
That is up to the landlord.
The last day of the lease.
No, just proper notice, if the lease so requires.
