You can refer the system requirements for Photoshop and Indesign both.
Also, If you buy a single license then you can install the app on two machines however, you cannot use both the machines at the same.
Thank you allot Mohit,
Also I have an Old version from ( Cs4 / Cs5 ), but I was not use it for years ago!
_?- Do you think the Licenses still activated and can I use it again !!??..
_?- And Please, Where can I found version of Photoshop cs2 working with Mac for download !!??
Yes, you can use the CS4/5 version, you just only need the correct setup file.
refer the download link: Other downloads
Also, please refer the below download and activation link for Photoshop CS2
Since they are all working at the same time, you will need SEVEN Creative Cloud subscriptions, since CC is the only good product for Sierra, and you want them all the same. I recommend looking at volume licensing, since managing seven different subscriptions will otherwise need seven different Adobe IDs. Forget CS2, it won't run on any of those systems at all.
