So I got back outside today to re-examine the mystery plant lol.. You guys were right! The vine w the flowers are a completely different vine from the one that the fruit are growing on.. The vine has some itty bitty thorns on it, they don't hurt at all & the texture of the outside of the fruit is completely smooth.. I've attached some pics of some of the babies & some of the more mature ones.. These do have a whiff of cucumber.. I can totally smell it.. Here's some pics..

I did look up the stinking gourds, they do look similar, but there's no yellow flowers anywhere.. I'll post a close up of the leaves..

Both Cucumis melo and Cucurbita foetidissima (Stinking Gourd) have yellow flowers, so these have obviously finish blooming. I'm sticking with my original ID of Cucumis melo . They are fairly common around here and like you said they smell like a mild cucumber. Farmers consider them a noxious weed since they will cross pollinate with cultivated varieties. The second vine looks like Jacquemontia tamnifolia as Danita said.

Another friend of mine said they could be plum grannies? I was just curious if these were worth keeping around or is it a weed that I should get rid of?

Plum Granny is a variety of Cucumis melo, it's Cucumis melo var. dudaim. They were also called ‘Queen Anne’s Pocket Melon’ because women of the Victorian era would carry them around in their pockets because of the sweet smell.

After researching all day & driving my husband crazy, I do believe that these are indeed plum grannies. I picked a small bowl-full and set them on my kitchen table & oh my! my house smells like honeysuckles! I probably won't be slicing these up (although I have no doubt they'd prob make amazing pickles, as odd as that is lol) but I am so delighted they decided to grace my yard! What a wonderful discovery!

They look more like Jay's second image above. Plum grannies are striped, like this:

Both of mine are the same. The one that grow around here sometime start out with light yellow on green stripes that fade to pure yellow as they mature. I think Candice's are like mine. Dudaim Melons are yellow and dark orange stripes. Mine, Candice's and Dudaim Melons are all the same Cucumis melo, just different vars. I have no idea how to tell the different vars apart other than var. dudaim has the dark stripes.
