how to connect a new AP 3825i to the administrator of ap's Extreme Network?

now on the Identifi wireless solution there is no way to "auto" discover AP

If the AP is in the same subnet/VLAN as the controller interface (that is enabled for AP registration) the AP is able to discover the controller.

I'd enable DHCP (with a small scope - IP range that isn't used by the active APs) on the controller topology and then factory reset the AP again.
The AP should get the IP from the controller and should be able to connect.

You'd delete the paired controller if you've only this one - as per the screenshot all APs are local = there are no foreign APs.

The problem is that the AP03 and AP04 do not connect and if I send a ping if they answer

Sorry but please confirm - are you able to ping the AP or not.
From which device do you ping from = is it the controller or a PC in the same subnet.

First we need to make sure that you are able to communicate from AP to controller.

Ok,

than you can use one of the discovery processes I described above.
The fast one is the way via ssh to the AP link one.

if you ping from a PC in the same subnet.
