You can apply a mask to any image. A mask helps to protect the area of your image that you do not want to alter. When you mask something, the inside of the mask is the area that can be changed. The mask tool in most design programs is depicted by dotted lines. Some masks are rectangular, circular, free-form, or auto-select.

To create an alpha mask for an image in Photoshop, you can use the "Channels" panel to select the channel with the most contrast between the subject and background.

Gaussian Blur blurs image but you can use it to soften mask edges and to create different effects like Glamour glow.
You can easily add blur using depth of Field in Guided Edit or from Filter > Blur > Gaussian Blur, Motion Blur... When using blur filter from Filter menu first duplicate layer with image, apply blur filter then create layer mask and use Gradient Tool on layer mask (set foreground background colors to black/white) to restrict blur only to some areas of the image.
A mask is a black and white image of the same dimensions as the original image (or the region of interest you are working on). Each of the pixels in the mask can have therefore a value of 0 (black) or 1 (white). When executing operations on the image the mask is used to restrict the result to the pixels that are 1 (selected, active, white) in the mask. In this way the operation restricts to some parts of the image. Some images like icons have a mask stored in them that is used when computing which parts of the image are transparent or not. There are two types of masks: layer mask which is pixel depended (described above) and vector mask which is a path that clips out the contents of the layer and is pixel independent. It is much easier to edit vector mask by the way using path anchor points.
No they don't, Gas Mask filters are designed not to go bad despite if the lid is unscrewed off, unscrewing the lid of a gas mask filter doesn't have any effect on the gas mask or it's filters.
