Airk covered most of the lambda matchup there. Fighting different lambdas is kinda hard imo because most have different weaknesses. If they have really fast 5d's jumping is a better option. If they like to go for anything else then 236X is your friend. If you miss the chance to punish a spike chaser don't block it because you'll lose a primer, super jumping and charging is what I usually go for but watch out for 6D.
Regarding act parsers way 22A is a good option not only against jumps but also 3C which some lambdas might use to beat out alot of tsubaki's normals, namely 5B. In this matchup I definitely think lambda is meant to be aggressive and use moves like sickle storm to keep pressure on, if they play like this you'll want to have meter for dead angles.
Most importantly, once you get in don't let her go without taking alot of damage or giving up a burst.
