in the bottom photo…. across the top is jewelweed, considered a help for poison ivy rash. the vine looks like Euonymus fortunei… an invasive exotic. agree with giant ragweed and passiflora. A rinse using soap is best for poison ivy prevention… try lye soap if poison ivy rash is present.

The bottom plant in the bottom picture is possibly a very young Great Ragweed. Looks like a possible passionflower vine in the lower right corner. The darker leaves in the lower left corner are possibly vinca. I’m farther from certain what the ones across the top of this picture are (perhaps young Chenopodium), but unlike the top two pictures, no poison ivy in this one. Too late for this time, but a quick rinse with water will usually be enough to deter poison ivy rash from developing.

#1 and 2 are absolutely poison ivy leaves
