Align items on different pages?

Did you look at the Edit menu? Paste in place is Cntl-Alt-Shift-V. 

Note that this works on same page orientation, so if you are using a facing pages document (left/right pages), objects copies from a right-hand page only paste in position on another right-hand page (not on a left page).

You could also use Object Styles:

Another option is to position the empty graphic frame on the parent page and override it on the document pages. (Cntl-shift-click is the override)

First, this isn't a forum for Express... it's for InDesign. I am not sure how much overlap there is to make answers here meaningful. But for ID in general...

Use guides. On the Parent page if need be, or set numerically on each document page. Or, just set them up numeically in the first place and copy the numbers from one to the other.

I am not sure you can do any kind of alignment across pages, and Paste in Place only works between matching page types (left to left, right to right).
