Welcome, Dorris. Starting roses from cuttings is kind of advanced for a beginner gardener to do. I think your friend, the self professed rose expert
might have set you up for failure here. Maybe ask them next time you talk to them if they would root some cuttings for you.
Unless you live in a very humid climate like maybe S. Florida, you'd have needed to mist those cuttings often and make sure they didn't dry out to keep the leaves alive until they formed some roots. Or give them a 'mini greenhouse' by covering with a jar or plastic bottle as Woofie suggested (which might cook the cuttings if the sun got to them).
Roses are not hard to come by, nor are they particularly expensive. I think you should treat yourself to a healthy growing rose plant in a pot and start from there. Even if all those cuttings had lived, it would be at least a year or two and lots of TLC before you'd see any flowers.
