Thank you for the confirmation. I've been looking about for a male for the arguta and a female for the kolomitka but haven't yet found them. In the meantime, I did pick up a pair of fuzzy kiwis at Lowes today (pollinator is Tomuri). Then I read on a website "The fuzzy kiwi male is the best pollinator and can pollinate the fuzzy or arguta female. The arguta male can pollinate the arguta or fuzzy female because bloom times partially overlap." Is this true? Can I just plant the Tomuri near the arguta females (I have 2) and it will serve as a reliable pollinator for them and the fuzzy female??

The first one needs more than a single flower, I think. Can you add leaf and vine and flower cluster photos? Trumpet vine is possible as is the related crossvine, I think, but see the link below to get more expert eyeballs on the problem. Second one definitely isn't poison ivy (I have lots of experience with it!), and actually looks more shrub-like than vine-like to me, but I have little expertise in southern plants. A great place to get plants IDed is on Garden Web's Name that Plant forum, which gets more traffic than this forum.

Does anyone recognize what it is? Does it look similar to anything you've seen before?

I have a couple of questions for you, without which we may not be able to guess the answer: Where are you? State, nearest big city, zone, if you know it. Is the vine growing in sun or shade? How big is the flower? (As big as a quarter? A dime?) How big is the fruit? Is it climbing into the trees or bushes, or is it along the ground?
