Does an object with more weight repuire more force to accelerate than an object with lighter weight?

It certainly does. That's why you have to push it harder to accelerate it horizontally.
But that "more weight" that it has is exactly the more force it needs for vertical
acceleration, and that's why all objects fall with the same acceleration.

Why is a heaver object harder to accelerate than a lighter object?
The difficulty to accelerate an object is related to its mass, not to its weight. However, on Earth (i.e., more or less constant gravity), mass and weight are also proportional. As to "why", I believe that is still an area of active research. We know that there is a property called mass, that causes gravitation, and inertia (i.e., a resistance to acceleration), but the exact nature of this property is still being studied.
The force of gravity on a 4kg object is twice that on a 2kg object Why does the 4kg object not fall with twice the accleration?
The reason that a heavier object does not fall faster even though there is more gravitational force on it is because it has more mass, and more energy is required to accelerate the greater mass. A small mass doesn't need a lot of force on it to accelerate it. It's "light" in weight. But a heavier one needs more force on it to accelerate it equally. Want a heavier object to accelerate the same as a lighter one? Apply more force. Gravity does that. Automatically. Think it through and it will lock in.
What happens to the buoyant force is greater than its weight?
If the buoyant force is greater than the weight of an object than the object will accelerate (assuming there are no other forces acting on the object)
What happens when an object falls to the ground?
Its weight causes it to accelerate. That is in simple terms. When an object falls to the ground, it still has mass, it still has weight, and it has constant forces acting upon it, such as gravity.
Does a heavier object or a lighter object experience a greater gravitational force?
I'm not exactly sure what you mean when you say "heavier" and "lighter". Does that mean the object's "weight" ? Could that be the same as the gravitational force on it ?

How does weight factor in when determining buoyancy?
The lighter a certain object is, the more likely it is to float, if the object is heavier, the object will sink.

What is the relationship between mass and a object?
Assuming the only difference is mass and that two objects have the same shape and size, it will take longer for the heavier object to reach terminal velocity than the lighter object. The terminal velocity of the heavier object is greater than that of the lighter object. Since the two objects accelerate at nearly the same rate at slower velocities, the time to reach terminal velocity will increase as weight or mass of the object increases. However I would not expect the increase to be a linear proportion since the drag is proportional to the square of the velocity.
How come a lighter object can exert more pressure towards the ground then a heavier object?
By distributing the weight over a smaller area.
Why is there a difference between the weight of an object in the air and it's weight in water?
Because of buoyancy ; something that acts in the opposite direction to the force of gravity to make the object feel lighter.
Why does racing bicycles weigh less than other kinds of bicycles?
racing bicycles are lighter because they are made of lighter materials, and less weight means you accelerate faster and that's what counts in racing..speed!
What both objects are made of the same material but the heavier object floats but the lighter object sinks?
If the object sinks or floats depends on mass or weight. The object can be made of the same material, but if the weight is not the same (say if it is heavery than water) it will sink.
Why is there a difference between the weight of an object in air and its weight in water?
weight of object in water = (Mass of object) time acceleration of gravity - Mass of an equal volume of water times acceleration of gravity. note weight of object in water can be a negative value.
