As others have mentioned, the majority (if not all) of your list of applications are installable on Manjaro.
There are several methods available including the official Manjaro repositories (preferred), AppImage, Flatpak, Snap and even the Arch User Repository (AUR) albeit not officially supported.
Are they “easy to install?” – that really depends on whether you’re willing to learn the methods needed – plenty of documentation is available in both the Arch and Manjaro wikis for most things.
In Manjaro you would mainly use the pacman and/or pamac package managers; the latter has a GUI:
The AUR should never be used blindly;
A question you might better ask (of yourself) is:
“Am I fully prepared and comfortable with diving into an unfamiliar rolling release distribution such as Manjaro?”
It seems to me that;
…a comparitively easier and ‘newb-friendly’ distribution…
that, you might have even more trouble with Manjaro.
Manjaro does require a greater hands-on approach than is often acknowledged; an understanding of terminal commands and how to troubleshoot your own issues is generally recommended; or at least the ability to provide enough accurate and useful information for others to assist you via the forum.
Kudos, if you’re already prepared for all that (and more). 
That being the case all that remains is:
