First year we have seen these, pics attached below. Only have one of the plant I thought was teasel, but I was told it was not. The second plant is in three different beds with multiple encounters. Any assistance identifying them would be appreciated.

Thank you,

    Did you mean to show two images? Only one is visible. A single leaf is thin information for an identification; if you have a picture of the plant in situ that would be better. – Colin Beckingham May 20 at 20:58

This one looks like Lactuca serriola, commonly known as prickly lettuce, compass plant, or milk thistle. As Colin states, a single leaf can be problematic for identification purposes, but I've seen enough of it that I would bet that's what this is. If it is, get rid of it now. It develops a dandelion-like seed head and will become a chronic pest.
