The small ones are the same as the one in the second photo. It's very common in Malaysia.You've got two different ones in the first pic.
The big one in the middle of the first pic is good tortoise food. I'm not sure about the other one with the serrated leaves. Is it a type of nettle?
Doesn't look like it, I will upload another pic tomorrow.The biggest one from your first pic is young sowthistle, great tort food
