What version of Premiere Elements do you have and on what computer operating system is it running? So generalizations for now.
1. With the mouse cursor draw a rectangle around the clips involved to select them.
2. Edit Menu/Copy
3. Move the Timeline Indicator to a clear location
4. Edit Menu/Paste
Adding clips to the Timeline, hold down the Alt key of the computer main keyboard as you drag you new clip to its place on the TImeline. Release the mouse first and then the Alt when done. Watch for changes in the tip of the mouse cursor.
C, Drag clips to the Timeline.
