Exercising with body weights as opposed to machine

I don't belong to a gym...so most of my exercises are body weight orientated only. I do have dumbells up to 5kgs, a 10kg disc weight, 5kg medicine ball and therabands...but that's it. My question is mainly directed towards my leg and ass exercises...will I be able to get toned and firm with what I have or do I need to start squatting etc with machines? If what I have is enough, do I need to do more reps perhaps?

All you need for now to firm up your buttocks and tone legs.

Add small weights if/when your reps become easy.
