As Mark suggested,

If you need to go back then you will have to uninstall the 64-bit and
reinstall the 32-bit versions.
You can have as many versions of SM available on the HDD as you have
space for. I currently have ten.
You *can* do that, provided you just unpack them from zip distributions
and don't install using the .exe installer. On Windows, the installer
registers some components with the system (mainly MAPI I think), and
having more than one registered at the same time can cause problems.
And, you can run them all from the
same profile or each from it's own.
The only caveat is, some versions alter the profile so that it does not
have the same information as the previous and so the previous version
might not work as expected with a later profile.
Well, it might work given certain caveats, but switching back and forth
between versions with a single profile is asking for trouble. There are
some well-known changes made by newer versions which aren't backwards
compatible. There are several more changes which are less well-known
and less significant or noticeable, but which can cause problems for
certain use-cases.
Most of the advice in the release notes is there for good reason. I
have been known to deliberately go against it, on a separate test system
so as not to break my day-to-day installation and profile, mainly out of
curiosity as to what issues are avoided by non-intuitive
recommendations. e.g. the advice to remove the master password before
upgrading between certain versions seems strange, and the upgrade does
*seem* to work if you don't do that - but only under some conditions and
there are cases where ignoring that advice can lose all your saved
passwords - so if you don't want to risk losing them, it's best to
follow the advice.
If you want to ignore the advice offered in the release notes and here
(including by those involved in the development, which I'm not) that's
up to you. But if you run into strange issues you could be on your own
when it comes to fixing them. Those who need to ask about which
versions can be used on their system and how to switch from one to the
other should certainly be directed to the supported way, rather than
unsupported suggestions which seem to work for some people.
