The drain pipe of my airconditioning is plugged This pipe runs through the wall to the yard and has one but most likely 2 90degree angles. I did cut the pipe in the straight line below the air handler( the unit is ceiling mounted) can I use draino or some other kind of caustic material to unplug it or will a snaking it work?

If you have access to compressed air that is the easiest way to open the drain.

Perhaps a wet/dry vacuum to suction any buildup from the condensate drain system.
