Does the 1993 ford aerostar XL 3.0L have 4 wheel anti lock brakes?

No, the 1993 Ford Aerostar XL 3.0L did not have 4-wheel anti-lock brakes (ABS) as standard equipment. ABS was not a common feature on vehicles in that class at that time. It may have been offered as an optional extra on some higher trim levels, but it wasn't standard on the XL.
