If I delete photos from photostream, will they be there on other devices?

I deleted photos off my iPhone and iPad that the world really doesn't need to see. Will those photos be deleted off of other Apple devices (mams iPhone, sister's iPod)?
Ps: We're all under the same apple ID

If you delete, anything from the photostream, it will syncronise with all other devices with the same account, and will delete from their too.

Anything you add or delete to photo stream, it get copied to other connected devices

  • Recovering photos from photostream? I have an iphone 5s and had a lot of pictures on my photostream. They all delete over time. Can I only have a certain amount of photos on photostream and they automatically delete once there's to much? Is there any way I can get the pictures back? Also by the way the pictures were never backed up on my computer and they aren't on my camera role
  • New photos not showing up in icloud photostream? I have the iphone 5, ios8. In settings my icloud drive is on and i have cellular data on. Photos are on w/ the my photo stream selected. Why do none of my new photos i take show up on my photostream on my laptop? Am i doing something wrong?
  • IPhone photostream vs camera roll, are they taking up too much space? I don't understand what is the point of having both. I have 1000 photos in photostream but 988 on camera roll… And they are of the same photos. Can I safely delete one of these albums and still keep all my photos? If so which one do I delete and how can I do it?
  • IPhone. If I turn off Photostream on iCloud will that delete all my pictures? On my iPone… If I turn of Photostream on iCloud will it delete all my pictures? I just wanna take icould off so all my pictures don't multiply & get added to iCloud. For some reason my bros photos get saved to my phone & my photos get saved to his. Needa take that off!
