Quick answer here, but every barbell exercise can be changed to a dumbbell exercise. While some machines can have positive benefits such as tricep extension, Machines aren't going to get you the best results. Here is an example:
Squat: --> Bulgarian split squat is not only a unilateral exercise balancing each leg, it is arguably better than the squat in some peoples eyes. It also lets you load up your outer glute muscles which are hard to hit without specific exercises. This can be done with dumbbells and a bench
Stiff Legged Dead Lift (SLDL) or leg curl--> these target two different areas of the hamstrings, so it depends on if you want to focus on hip extension, or knee flexion. Leg curl is a machine exercise. if you want to do a stiff legged deadlift, you can use two dumbbells and hold them in front of your legs width-wise, as you would a barbell, and do the exercise. You can also do one-legged versions of this as well to increase difficulty.
Leg press: 2-3X10-12/2′
Another leg curl: 2-3X10-12/2′
Calf raise: 3-4X6-8/3′
Seated calf: 2-3X10-12/2′
Tuesday: Upper Body
Flat bench: 3-4X6-8/3′-->use dumbbells on a flat bench and do a dumbbell bench press instead
Row: 3-4X6-8/3′-->you can do T-rows, one armed rows, supinated rows with dumbbells, or use a cable machine to do cable rows, which you can do low cable rows, high cable rows, or horizontal rows.
Incline bench or shoulder press: 2-3X10-12/2′-->easily substitute dumbbells and do an incline dumbbell press or a dumbbell press
Triceps: 1-2X12-15/1.5′-->this isn't specific but you can do tricep extension or tricep pulldown on a machine
Biceps: 1-2X12-15/1.5′->dumbbell curl, incline dumbbell curl, or concentration curl, one armed preacher curl with dumbbell
