@Orbela, where are you located? Is it Calfornia? If so, the first one is wild buckwheat, safe.
The second is wild mustard, safe but your tortoise may not care for it.
If in California, the third may be Desert Willow, which is safe for desert and steppe (Russian) tortoises; I’m not sure about Sulcatas.
I feel I know the fourth as well but can’t put my finger on it just now.
