It depends whether it's a concave or convex lens. If it's a convex lens - the thickest part is at the centre. With a concave lens, the thickest part is around the edge.
Basically most video cameras are fixed lens so you cannot put a camera lens in it unless it is specially built.
Yes I can --> can you?
In a camera with a removable lens system, the camera body is all of the camera except the lens mechanism. Many more-sophisticated cameras employ a system of removable/ exchangeable lenses. The "camera body" and the "lens" are often sold separately. What is called simply the "lens," though, is really a lens tube with multiple lenses and multiple adjustment mechanisms. It will have a standard connection point that mates to the lens mount on the camera body.
The functional opening is the aperture, the opening that controls the amount of light that hits the photosensitive surface. You may have a camera with interchangeable lenses that screw into and out of the camera's body. The opening into which the lens is screwed is not the aperture.
The iris. - - - - - No. It's the eyelid. The shutter's function is to completely stop light from reaching the film (or the sensor, if you have a digital camera with a mechanical shutter). The iris in your eye cannot do this--only the eyelid can.

A diverging lens is thickest at its center and gets thinner towards the edges.

This part is called a Lens, on the camera and the glasses the are made of either optical glass or optical plastic, in the eye the lens in an organic material. Lens allow light to enter the camera, eye or glasses, and focuses that light on a surface such as the camera's film, the eye's retina, and the glasses wearer's eyes.
You need to change the focus on the lens. There should be a part around the camera lens that turns, this will change the focus of the camera.
Instead changing lens, which is not an usual procedure, it would be advantageous to purchase a new camera that has the kind of lens you are looking for. Normally, lens is a part of the camera that can't be changed, except on expensive models. In this case, changing the lens is an easy procedure that can be checked on the user manual.
The lens of the camera is responsible for focusing incoming light rays onto the camera sensor. The lens can be adjusted to control the focus and sharpness of the image being captured.
Yes, a convex lens is thickest at its center and tapers towards the edges. This design helps the lens to converge light rays towards a focal point, which is used in applications like magnifying glasses or camera lenses.
