What equipment should be used and how i can do the Configurations

Hi,

In this case, first of all you'll need a WLAN planner tool (https://support.huawei.com/enterprise/en/tool/wlan-planner-TL1000000028) to properly map all the APs in simulation to cover all the area in a blanket coverage manner.
For password security option, Huawei WLC has a built-in guest/BYOD portal, you can use that.
For prohibiting iphones, you can use WLC's device management feature and can stop iphones to connect to the WiFi networks. For configuration guide, please use the following guideline:

To properly size the number of APs, WLAN Planner tool is a must. Secondly, you'll need WLC to manage all APs, thirdly, POE switches and a aggregation/core switch where all of these will connect.

I hope it is helpful. If you have any other specific question, please do share and will try to answer it

Based on the information you provided, I think AC6005 could meet your requirement.

To prevent the iPhone devices from using the network, I think you can use terminal identification to find out these devices, and block them in the STA blacklist.

please check Terminal Identification and STA blacklist
