If you have two parachutes, one big and one small, the biggest one will take more time then the other parachute. This happens because there is more room in the parachute which is causing air to go in side, which is air resistance. The smaller parachute has a lot of air resistance because it is smaller and there is less room for the air to go inside. However, the bigger balloon has little air resistance because it has more room in it for the air to get inside. The air is pushing the balloon up so it will fall slower.
Parachutes are interesting aircraft. The major retarding force of classical round parachutes is drag. Weight and drag determine their rate-of-descent. But air spills out of them because they oscillate, too. Since the 1960's parachutes have been designed that acheive lift from their forward motion.
The surface area of a parachute can be different sizes and weights. If the surface is smooth then the you will fall faster because the texture is smooth and the air will slip by it. if it is rough then it will be slower because the the air will come into the parachute slower.
yes.
Probably, all else being equal. Smaller heads would mean less air resistance, unless a head is bigger but shaped more aerodynamically.

Depends what you mean by "better". A bigger parachute provides more wind resistant so if you were to jump out of a plane, you would want to go big. If your talking speed (like a running parachute) you would want a small parachute to accommodate how much harder you want to make your run
cross sectional area for air resistance is greater as you increase the parachute size.
This is because the parachute will trap air underneath it and so the force of air resistance will increase, and it will take longer to fall. The bigger the air resistance the quicker the terminal velocity is reached.
yes because bigger ones get a lot of wind speed who make them move fast but the smaller one can't not movee at the wind speed
If the hole is bigger the parachute speed will decrease

It really depends on what you're using it for, and the experience level of the parachutist. Bigger parachutes are safer and fly slower, and are ideal for students and beginners. Experienced skydives often use very small high performance parachutes in order to fly very fast horizontally, close to the ground (known as "swooping"). However, one of the most common causes of injury and death in skydiving is inexperienced skydivers flying parachutes that are too small for them to handle.
yes.
they are about the same. it really depends on the type of backpack or parachute backpack you are talking about.
Make the parachute wider/bigger or make the parachute deeper. Make the thing pulling it down lighter. Hope this helps. =)
