The angle of attack in glide- how high can it be?

[inviscid-lift]

My question is, how high can be the angle of attack of a hang-glider, paraglider (the canopy) or a sailplane, gliding in still air.

Assuming a small glide ratio of 4:1, tha flight path is at 14 degrees with the horizontal line. If the glider was at the angle of attack 14 deg, that would mean he is parallel to the horizontal.
I understand, that the possible correct AOA are >0 and <14. Is this right? Is it possible for the AOA to be higher than 14 degrees?

Stalling would typically occur at $$\alpha > 14^o$$more or less, this is not a cruise AoA. Any aircraft typically can cruise at $$-3^o<\alpha_{cruise}<5^o$$. I am not sure about hang gliders but I would assume the same would apply since it is only a flying wing.
