Yes, you can. Instagram allows you to share other people's IG stories to your own story. Just look for the share icon (usually an arrow) on the IG story you want to share, and then select the option to add it to your story.
First, make sure you are using a platform that has a'story' feature, like Instagram or Snapchat. Then, look for the option to create a new story.
