I think that an A frame is the way to go as well. The torsion loads on a straight beam like that are going to lead to failure. A triangular frame will be under compression forces instead of shear forces for the most part. Having 3 swings increases your span as well, so I’d go for more than the 2×6’s. 2×8’s or even better 2×10s would be my choice for the top beam.

Anything worth doing is worth overdoing….
