1) Stop hunching.
2) With those weights, you won't be able to make anywhere near the sorts of gains you could make with, say, an Olympic standard barbell, 2x20kg plates, 2x10kg plates, 2x5kg plates, 2x2.5kg plates and 2x1.25kg plates (a cumulative total of 97.5kg, or ~215lb). With this equipment you could do more efficient exercises and have much more potential progression...and then all you'd need longterm to keep on getting more progression is nutrition, consistent training, and buying an extra couple 20kg plates once a season.
3) That said, some things you can do with the weights you have are: lunges, split squats, bridges/hip thrusts, overhead press, bicep curls, skullcrushers, one-arm rows, floor/board chest press, lateral raises, weighted chins, weighted dips, weighted core exercises. And with these exercises, you can certainly get a little bit of muscle and strip away some excess fat, provided decent nutrition for each goal.
4) For nutrition, to build muscle add 250-500kcal into your current diet every day and consume 1g protein/lb bodyweight/day. To decrease fat, reduce 250-500kcal from your current diet every day, and consume that same amount of protein. Eat plenty of fruit and vegetables, meat, whoelgrains, nuts, legumes, and drink plenty of milk and water.
