Do different shaped parachutes with similar surface area have the same travel time?

If i drop a rectangular and a circular parachute with the same SA, from the same height and at the same time, will they both land on the ground at the same time (assuming everything is constant)?

Depends. Standard round parachute canopies are primarily drag based, but rectangular ram-air parachutes are designed to develop significant lift with forward airspeed. Ram-air parachutes often have less surface area than standard round canopies, but because of the lift can stay airborne for quite some time, like a glider.
