The Layers panel is where the majority of your work with layers will take place. Let's examine it in detail.
To crop a layer in Photoshop without affecting other layers, you can use the "Clipping Mask" feature. Select the layer you want to crop, then go to the "Layer" menu and choose "Create Clipping Mask." This will restrict the visibility of the layer to the shape of the layer below it, allowing you to crop it without affecting other layers.

To copy a mask in Photoshop, you can right-click on the mask thumbnail in the Layers panel and choose "Duplicate Layer" or "Duplicate Mask." This will create a copy of the mask that you can then apply to another layer or make adjustments to.
To crop individual layers in Photoshop, first select the layer you want to crop. Then, use the Marquee tool to create a selection around the area you want to keep. Next, go to the "Image" menu, select "Crop," and the layer will be cropped to the selected area.
There aren't any disadvantages to use multiple layers. Multiple Layer Design is the point of using Photoshop. You can change elements of a project one piece at a time rather than single layer apps that once you make a enough changes you can never go back. In Photoshop, you can create everything in a Non-Destructive manner and Multiple Layers is a foundational feature for that.
Layers are pictures stacked one to another, Layers can contain transparent pixels so you can see through Layer above what is on Layer below.
To add a layer mask in Photoshop, first select the layer you want to add the mask to. Then, click on the "Add Layer Mask" button at the bottom of the Layers panel. This will create a white layer mask next to your selected layer. You can then use the brush tool to paint on the mask with black to hide parts of the layer, or with white to reveal them.
Whenever I create a new layer on Photoshop, it's always created above the active layer. Is it possible to change that behavior and make it so that whenever I create a new layer it's created below the active layer instead? My objective with this is so that whenever I import an image it goes below the previous one and not above.
To sum up, there are two primary types of masks in Photoshop: layer masks and clipping masks. Layer masks use values of gray to assign levels of transparency to specific portions of a layer or group of layers while clipping masks use the transparency of one layer to define that of a different layer or group of layers
