how to configure static lan ip to different router provided by isp?

We have got Vodafone Internet ISP. We asked for 5 public ip's.

They had provided 1 wan ip and 5 lan ip pool.

WAN Configured and internet working but LAN ip how to use, i need 5 static ip address to use for 5 different devices.

Set up devices with static addresses manually, or use DHCP. Use the addresses assigned to you.

Vodafone's static IP CPE screenshots imply enabling this is hidden under expert settings, "LAN Public", "Multiple Static IP".

Also consider implementing IPv6, which sadly is not visible in the Vodafone screenshots I found. Easier to understand when everything, including LAN devices, are assigned public IP addresses.
