Weights can provide one form of resistance. But in terms of exercising, resistance means anything that makes you work harder.
Pushing against an immovable object, such as a wall (isometric exercise) provides resistance, as does pulling against a thick rubber band (Bowflex and similar exercise machines). Even walking or running uphill can be considered resistance, as you're fighting the pull of gravity against your own body.
The weight of the riders does not affect the amount the ride can lift since the system is designed to lift and carry the combined weight of the riders and cars. Air resistance is a factor that the ride must overcome to lift riders into the air.
The amount that a healthy person can lift depends on their height and weight.

Yes, the weight of 100 dimes is approximately 5.5 ounces (156 grams), which is typically manageable for the average person to lift with one hand.
OSHA does not have guidelines on how much weight one person can lift. However the lifting guidelines from NIOSH suggest a maximum of about 40 pounds.
The forces acting on a plane flying at a steady height are lift, weight, thrust, and drag. Lift is generated by the wings and opposes the weight of the aircraft. Thrust is produced by the engines and counters drag, which is caused by air resistance. At a steady height, these forces are balanced.
A combination of the thrust of the engines and the lift of the wings overcoming the drag of air resistance and the pull of gravity.
It would take roughly 67 weather balloons to lift a 190 lb person. Each weather balloon can lift around 3 lbs of weight, so dividing the person's weight by the lifting capacity of one balloon gives the approximate number needed.
There is no US regulation setting a maximum weight that an employee can lift. There is guidance available on that point, however, from NIOSH among other sources.

it is that a person does not ave to lift as much weight
