Need Advice Please

I've been working with dumbbells for three months at home, 10KG dumbbell each arm, the exercise I have been doing is,

Should Press
Bench Press
Curl
Sit Up
Push Up
Cardio

Each exercise I do is 25 reps for 2 sets

I'm 17 and my target is to get a visible six pack, chest and biceps without tensing, I don't drink protein shake, I've breakfast, lunch and dinner either rice or pasta

What other exercise should I be doing?

Barbell Squats 4x 6-8

Do Compound exercises. Barbell BenchPress, Deadlifts, And If you want bigger arms do more sets of less reps (4 sets 6-8 reps) with heavier weight

Thanks, since I don't have a weight bar but only dumbbells, the technique is the same?

Also the exercise I do, should I break it down to more sets or keep it as 2 sets with more reps?

What should I increase the dumbbells to? Currently doing 20KG (10KG x 2), also using heavier weights will allow me to build and strengthen muscles?

Can someone help me please

Is there any way you could get a gym membership, heavier dumbbells, or a barbell & weights? You can't build much muscle with 10kg dumbbells, sets of 20+ are going to be training endurance instead of inducing hypertrophy.
