You can use "lightbox instagram widget" to show the your insta feeds on home page.
Use this link then login using your account details.
Once you login then you can do the setting according to your requirement ie. how many images to show, need to show in slider or grid, responsive etc.
Hey there, @Alvin--R
Boo here from Shopify Support!
Great question. There are a number of ways to integrate your Instagram Feed to your online store. Some Shopify themes have this built-in, here are our themes with a built-in Instagram feed.
If you are looking to add this feature to your current theme we do have a good few apps, all with their ratings clearly available here.
A third option would be to get a Shopify Expert to build this feature for you.
All the Best,
