Do computers on the same Internet have the same IP address?

No. Most personal computers are configured to ask the WiFi router to assign them an IP address upon joining the network (using DHCP). Most good routers will assign a unique IP address to each machine (particularly each network interface) a different IP address.

Can two network have same IP address?

As I understand it, two computers cannot have the same public (external) IP address unless they are connected via the same router. If they are connected via the same router, then they can have (share) the same public IP address yet have different private (local) IP addresses.

What happens if two devices have same IP address?
