Can I upload other peoples photos to instagram?

Yes you may! People do it all the time. You can give credit to where u got it from in caption. Like for example write (via email) , google, Facebook or etc. but that's if you want to put it up there. It's just photos, people are not really going to say anything. As long it's not a picture of a regular person that you don't know then you shouldn't do that unless you have permission to do so. If its celebrities, family, friends, even cars or any type of object you could put on Instagram.
