None of the plants you mentioned showed up on the poisonous plant list from UCDavis that I cross reference on.

Carthamus tinctorius (Safflower) can cause dermititis, itching.
Luffa cylindrica- the bitter types have poisonous parts. I don't know how closely related to
luffa acutangula, "angled gourd loffa," it is.
If you know the genus and species of a plant,
http://davesgarden.com/ is often very helpful for plants I am unfamiliar with. Along with other plant details, they typically list if there is or is not any toxicity reported with a plant. *I don't know if you have to be a member or not to use their search engine.
I grow a number of plants in my yard that show up on many different lists as being poisonous. However, keep in mind there are vary degrees of toxicity in plants. Some plants cause mild symptoms like itching, and that is still considered toxic, but it won't kill you, your pets, or your chickens typically. I look out for plants listed as
deadly or to have Major Toxicity. The worst offenders in my yard only cause gastric problems, and are usually listed as having minor toxicity. The chickens leave those alone, and if they have taken a nibble, they never bothered them again.
Here is a short easy list of stuff people commonly grow around by me that could kill the chickens or me if I ate them:
I don't plant or ever recommend people plant these, even though they are sooooo pretty.
Oleander
Brugmansia sanguinea (Angel's Trumpet)
Foxglove
Datura stramonium (Jimson Weed)
Larkspur
Nicotiana glauca (Tree Tobacco)
Castor Bean
English Yew
*I watch out for mushrooms in the yard, too.
So many of the online lists are daunting to non gardeners and gardeners alike and are aimed more at human toxins, but agencies like the SPCA apply them to animals as well. I waded through a lot of the different lists when I got a baby tortoise 5 years ago, and then again when I got chickens. I finally decided to worry only about the worst offenders that are deadly. My animals leave all the mildly toxic stuff alone. I would have no garden left if I only planted stuff that was healthy for the chickens to eat. Good Luck.
Here is my list of chicken resistant plants so far.
