How can i log out of my mac from my android phone

You don't. If you are talking about getting out of iMessage because you no longer have an iOS device, then see this support document. Get help if you can’t receive text messages from an iPhone - Apple Support or this link https://selfsolve.apple.com/deregister-imessage

If you are referring to something else, then please explain better.

No idea what you're talking about. You can't log into iCloud with an android device, therefore you can not log out of it from your android device.
