How to make a selection in one photo and move it to another photo

Question

I have always used Photoshop Elements, from 7 up to 12.  I just bought Photoshop CC.  I am totally confused over it.  There's not photo Bin, that is where I use to drag from the open photo down to the one I wanted the selection in.  I tried doing it
by making the pictures smaller and dragging them down to the bottom, but then things got messed up and every time I opened another photo to use it open on top of the previous one.  To me this is important as this is what I have done
in Elements all the time.  I can learn the other stuff about Photoshop later, but this one thing is important to me to be able to figure out.  I make pictures for people who have lost their pets or for birthdays and use a lot of digital scrapping stuff in
them.  It's always been easy to do so, but now I am totally in a daze over how to do it.  Always wanted Photoshop, but I only have 30 days to decided if I like it and if I can't figure this one thing out I will have to return the program.  Can someone
point me in the right direction for some tutorials on how to do this one thing?

Oh,  and I'm not sure what you mean Load Files into Stack.  ??????
In the menu Edit there is an item Scripts and there is an Item Load …
If you want to rescale, rotate, … parts of your composition you should work with Smart Objects.
So see if Photoshop > Preferences > General > Palce or Drag Raster Images as Smart Objects is checked and then use File > Place to put the elements into your layered file.
Whenever you need to adjust one select it in the Layers Panel and invoke Edit > Free Transform (cmd-T).
The advantages of Smart Objects are numerous:
• multiple instances of a SO in a containing document that update simultaneously on saving an edited SO (please note that for a SO to maintain a connection to the external file one needs to use File > Place Linked instead of File > Place Embedded )
• the possibility of placing vector content as Vector Smart Objects (though this will output as pixels)
• non-destructive application of Filters
• non-destructive application of transformation, warp, puppet warp (not all of these are available for Vector SO, but by converting such a one to a regular SO they become applicable)
• combination of elements of different color spaces
• the ability to Replace Contents of SO (for example when faking as-of-yet non-existent products by mapping packaging design elements onto images of a blank container and the design is likely to change)
• Stack Modes for certain combinations of photographic images
