Hi All,
Does someone know in JOSM if it's possible to select more than one
building, lets say a group of buildings and square them at the same time?

It's funny, I was having the same idea recently while using the JOSM
validator on "finished" areas of TM projects.
JOSM validator already has a big red error category for duplicate
buildings (where there is 100% overlap). This crops up a bit in our
finished projects, but it shouldn't really. It's a clear data error.
We should always fix duplicate buildings. ....So I start by fixing them.
Then there's a JOSM warning called "crossing buildings". Again this is
always a data error actually, and ideally we'd fix all of these, but
these are very common in our finished tasks. Every case where a
neighbouring building is drawn over the top of the other, even ever so
slightly. (Often we see buildings up against each other in the
imagery. To be purely strictly correct, these should be mapped as ways
sharing nodes, but it's understandable that folks don't always get
that quite right, and it doesn't actually matter that much). I
sometimes spend ages fixing all the "crossing buildings" warnings, but...
...among these there are some cases which are more important to fix,
where buildings are actually a kind of duplicate, but not 100%
matching. The same building drawn in twice by two different people
(probably due to mapping at around the same time).
So I've just been trying this script by first fixing the 100%
duplicates using the normal JOSM validator error, then next selecting
these cases using the script. It works! But it's a bit fiddly to
set-up and use. I was imaging this kind of logic, but as a refinement
to the JOSM validator itself. Under the "crossing buildings" warning
list it could show the major/minor types of crossing buildings.

more than 50%
Mike Thompson was kind enough to build me a JOSM script.
https://github.com/MikeTho16/ JOSM-Scripts
<https://github.com/MikeTho16/JOSM-Scripts>
SelectDuplicateBuildings.js
To Run:
* Install JOSM's Scripting Plugin
* Place above file in a convenient location on your system
* Click "Scripting" (on top menu bar)
* Click "Run"
* Click "..." button and select this file.
* Click "Run"
Selects duplicate, or near duplicate, area buildings in JOSM's active
data layer. A "near duplicate" is a building whose bounding box
overlaps another building's bounding box by more than 50% (I couldn't
get a pure area compare to work). Only the first building encountered
of an overlapping pair is selected. The selected buildings are added
to the current selection.
Note clear the selection first then use the todo plugin to go through
the duplicated buildings.
