Need Help Identifying These Flowers

Any ideas what they are? I appreciate the help. Thank you!

 

#2 looks like Eclipta.

 

Hey, thanks! I think it is.

 

#3 looks like some sort of Cleome.

 

Thanks David! I looked it up further and found it to be Cleome rutidosperma or Fringed spiderflower.

 

#4 looks like a Penstemon ... where were these photographs taken?

 

Hi! Thank you for the reply. All four were taken from my backyard. The flowers grow wild. I hope that helps.
