Need help starting a workout routine with whats in apt gym

Im 5'11 24 y/o male and about 185 pounds im trying to primarily lose weight and overall be healthier, i have access to the following, dumbbells, treadmill, medicine balls, and some kind of "all in one station" with a wieght setter, an overhead pulley bar(i think its name is a lat bar?), a pully system in the center and metal bars that you push upwards. Ive never been really to a gym or had most of this stuff explained to me outside of like 1 health class lesson in freshman year of highschool. what would be an effective workout routine with this so far ive gone the past 2 days focusing on cardio (and learning how out of shape ive gotten x.x), bicep curls 3x10, weighted squats, and pushups 3x10
