Is it like the same layout with the same info in it,
or same layout with different info in it?
If it’s the same, it should just work out of the box. Edit the component and all will be updated.
If its different info inside, you probably have to connect the title and internal fields to be able to change them because the connecting thing make it dynamic instead of static.
So without connecting it is as is. change 1, change all.
When you connect the fields, you should be able to put other info inside.
To be honest, i don’t use components at all. I use templates for what’s the same, and just copy an already made element to another page and change its content.
There are some steps to take with components and reading the manual would be advised.
And it should be purple like the image below:
