Poison Ivy, Oak?

I've looked up to see if this is poison etc.

I don't think it's sumac

 

You're showing more than one kind, most of the shots are Parthenocissus. The 4th one however looks like Celastrus.

 

The fifth photo looks like Poison Ivy to me; but, if it is, you should know by now, unless you're immune to its effects.

Look at the stems, including the tendrils

 

I didn't know what to make of those stems; but, now that I look at the photo more closely, I realize that the leaflets are way too small to be Poison Ivy.

 

I would follow what Ron advised, - no matter how big are the leaves it does look like poison ivy.

 

Dahd Dee - if you're following, did you suffer any ill effects from touching the plant in photo #5?

 

Fairly certain the last one is not poison ivy (leaf size is not a reliable indicator on this most variable of plants). Ron pointed out tendrils, and it looks like there is a suction-cupped tendril (Parthenocissus) in front of the forefinger in that photo.
