a) Any modern gliders are using NACA type airfoils?

Nope... I'd estimate since at least 50 years...

b) Whether anyone knows what the parabolic equation of the ASG-29
profile?

If you men the parabolic equation that defines the camber and
thickness distribution of NACA airfoil:

Laminar airfoils that are used on gliders don't use parabolic
equations - their shape is defined by calculating the shape based upon
pressure distribution.
