How to Clone Bootable SD Card?

i'm suspicious of a couple of these suggestions; Android, as an example, uses Windows systems for a lot of tasks [very clever of Google to plan such and incorporate]. there are hidden files there that do not easily expose unless other utilities are used. I would imagine that to be true with SD cards used on other linux systems.
so, my fault, but let me be more exact:
Case 1: Windows 7/8/10-bootable SD Cards with programs and data. What package to use, and do the cards have to be EXACT matches, CLASS matches, and/or Size matches [assuming the total space required is adequate]

Case 2: SD cards formatted for use on Android [OSX?] or other Linux distros - can these be cloned using Windows and how?

if i had a range of cards I would do some experimenting but unfortunately I don't. have 2 different 8gb heavily used and not to be tampered with other than the above; 2 16GB, 1 32GB. And actually a couple of these are micro-sd using usb adapters, typically

win32diskimager clones everything for windows, linux or android. So long as receiving card is big enough it works.
