top one is golden rod or Solidago.
the second is one of the mallows, Malva possibly moschata but dont know which specifically.
third is either an azeala or rhododendron. cant tell as cant decide on the size.

Hi, Aimankay!
On the third picture, the growth habit is more like a Rhododendron than an Azalea. The second picture looks like a Sidalcea to me, but that depends on the shape of the leaves, which I'm not seeing very well. The first picture is definitely a goldenrod, like Seaburngirl says.

A rule of thumb though not infallible is that a rhododendron has 10 stamens and an azalea 5.

Thanks everyone
