Histo-Tips: When trying to differentiate between veins and arteries, look for clearly defined layers (usually arteries) or the size of the lumen (usually collapsed in veins).
I'm not sure this is mesenchyme - but I also am not sure in what tissue you took this image. Mesenchyme typically has has spindle-shaped cells with processes that extend from them (see pg. 158 in your book). Try to find an image that looks more like that- there should be slides with plenty of mesenchyme (see last year's image: https://bcrc.bio.umass.edu/courses/spring2017/biol/biol523/content/mesen...).
