As regards point 2) it says Copy. So I leave the original 'MSN Messenger' folder in the Programs Folder. It is not a cut and paste but copy and paste.
That doesn't matter. You can copy it or rename it, it would be the same result in the end.

No, you will see only 1...
There is some wrong info given in this thread though:

It sure does matter... You need to install the older versions first!
------------------------------
The reason why you need to copy, rename or move the original MSN Messenger folder is to keep the old files.
After this, you install a newer version. This will overwrite the existing files, if they still exist. That's why it doesn't matter if you copy, rename or move the original folder.
But!!!! dispite popular believe, there are always things to be considered when doing this.
MSN Messenger does not only depend on the files you'll find in the MSN Messenger folder.
When you install a version, files of that version will be installed in the MSN Messenger folder, but also many libraries are installed/updated in your Windows System folder, and many stuff is updated in your registry.
This makes that, after you installed a newer version, it is quite possible that the older version might not work 100% anymore because the libraries and stuff are not from that old version anymore! So, in fact, if you use the old version, you are actually always using the newer version's libraries and registry settings (because the old ones do not exist anymore as they are always overwritten)! And there is no garantuee that these new libraries and registry settings are downwards compatible at all.
This is also the reason why you must install the
old version first and only afterwards install the newer version. If you do it the other way around, compatibily problems will occur for sure since the new version is then using old libraries which quite often do not support the new functions.
In fact, there are many errors which can occur by using two versions like that at the same time. And many connection problems or other "strange" stuff occurs because people have messed with such things and/or using two different versions at the same time (even if they installed the old version first).
This is also one of the reasons why MSN Messenger does not have polygamy enabled by default: To prevent people from messing around with different versions and thus having compatibily problems.
------------------------------
Now, some might say it works fine with them. That is possible, but that doesn't mean there could be problems in the future, or that they never had a problem with connecting or some feature from time to time or other stuff. And it also doesn't bring down the fact that they are using program files mixed up with libraries from other versions, etc...
