I found out how to do what I wanted and I'm giving my steps in hopes that it might help someone else. I wanted to put several photos from a file onto a new blank image. This is what I did.
1. Create a blank page. File/New/ Blank File. Put in the size. I used 8x10.
2. Bring the photo you want to use into Elements as you always do. It will list along the top next to the blank sheet.
3. Choose SELECT (top of screen)/ Select All.
4. Choose Edit/Copy or Command "C"
5. Click on the Blank File. Chose Edit/Paste or Command "V"
6. Click on Image/ Transform or Command "T". There should be a dotted line around your pasted image. You can then move and adjust the image to how you want it. When finished, press the check-mark on lower right of photo.
7. Repeat this with all the photos you want on the new blank file.
8. You will see on lower right of Elements, the background layer and as many layers as you have photos. These layers need to be permanently placed on the background layer. Go to Layers and press Merge Visible. This will merge all layers to the background.
9. Save as and you are done.
For Step 6, you can just click the Move tool to do the same thing. As for merging or flattening layers, if this is something you often want to do, just keep the layered copy and then you can just swap out the images for the ones you want this time. Also, if you save as a JPEG, that makes an un-layered copy automatically.
