I have lumia 525 which has 1 GB RAM. So as per hardware requirement for windows 10, 525 is eligible for windows 10 updates. But I haven't found 525 anywhere in the list of devices which will get windows 10 update. So I want to confirm it.

The 525 won't get the official Win10M update.
You can only install it via the Windows Insider route.

Right. No X2X serie. Requirements are 1 GB RAM + different than old S4 chipset
But you can use released to them Win10 build 10586.164 on your phone entering in Windows Insider, Release Ring, and use it till you want
