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 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.
To change the color of the background layer in Photoshop, first select the background layer in the Layers panel. Then, go to the "Edit" menu, choose "Fill," and select the desired color from the options. Click "OK" to apply the color to the background layer.

To mask an image in Photoshop, you can use the selection tools to outline the area you want to keep visible, then create a layer mask to hide the rest of the image. This allows you to easily edit and manipulate specific parts of the image without affecting the rest.
One layer.
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 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
Every image contains at list one layer but you can have as many as you want. Layers are separate images which can contain transparent areas or different levels of transparency. People use layers to create compositions in Photoshop because every layer can be edited separately without affecting other layers or composition. Another advantage is because you can save layered image (PSD, PSB, TIFF ) and edit layers at any time you want. Photoshop offers several type of layers like Type layer so you can change typed text only for example. When it comes to save image you can flatten image or to save flattened version of image on disc and leave composition as it is with all layers for further editing at later time. In other words saved layered image serves as template which can be edited even after 10 or 20 years.
To unlock layer press padlock icon on top of layers stack on LAYERS palette, when padlock icon on right side of layer is gone do what you want to do with that layer.
To Flatten your Layers in Photoshop simply go Layer>Flatten. I recommend saving your image as a psd before you flatten so that you can refer back to your layers. Then flatten and save as a jpg.
To select all layers in photoshop for a PC open up your layers window (It is under window - layers), hold down the shift key and click on each layer that you want to group together or edit.
Select layer You want to transform (click on it at LAYERS palette) then press Ctrl + T.
You can not separate flattened layers (they have becomed one layer), only from history to go to step when you have flattened image.
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.
Layer is basicaly image which can have transparent pixels. Every image have at list one layer. One image can consist from at list one layer and at most hundreds or thousands of layers, in Photoshop only limitation for number if layers is your computer memory.
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.
