Picture 1: I don’t know what the fluffly looking plant is but the smaller ones underneath are a dandelion relative: safe.
Picture 2: don’t know.
Picture 3 has more dandelion relative and the lacy one is yarrow: safe.
Picture 4 looks like bittercress to me. If not that a member of the same family: safe.
Pictures 5 and 6: don’t know.
The tortoise table says yarrow isn’t safe?
