Multi-bootable USB

Hey guys from TPU, couldn't find any specific thread pertaining to the question asked on title. As mentioned, I'm trying to create a bootable USB, but with many specifics boots available.

I've been trying to create one with multiple boot device including one that enables me to run Windows 10 directly on the USB Thumb Drive but to no avail.

The list of bootable images i'm trying to create are

1. Windows 10 (A full OS running from thumb drive)
2. Windows 10 ISO (Bootable disk image for fresh install)
3. MemTest86+

Have tried YUMI or UUI from the website USB PenDrive Linux but as this is my first time, i don't know how am i screwing up or am doing it right.. Anyone got a rough idea on a step by step guide? Thanks!

Best way to make a bootable Windows 10 image on USB with all existing software, drivers & configurations to deploy on exactly identical hardware?

There is no difference in the hardware we want to deploy that image on.

Planning to deploy this image on over 4000 desktops of same hardware configuration and make and model.

Is there a freeware/opensource/free software that we can use for this purpose commercially?

can you suggest a solution and KB article where it's step by step explained how to achieve it or do it?
