Out of my comfort zone. NA Pottery

Hello Friends. Picked up these five NA pots for $10.25 (for all) at the thrift store today.
I know little to Nothing about this kind of stuff but of only $10.25 I thought I'd take a chance. I know they aren't old, but each is signed. I can't make out most the siggys becauce they are just incised in the white clay, but 2 are signed in marker. Anything you can tell me about them would be greatly appreciate. As always, Thank You in advance!

 

Thank you @*crs* Very helpful indeed. I appreciate your help. Looks like I may have done a little better then I thought!

 

They're modern style, but even this pottery ignoramus knew that was a good deal. Dinè means "the people" or close enough - about the only Navajo word I know. It's their name for themselves.

 

These look like modern Navajo pots. Probably bought as green-ware and decorated by the artist. Not traditional hand coiled Native American pottery. The Navajo actually don't have a tradition of pottery making so Navajo pottery is a relatively new phenomenon. Not terribly valuable but well worth what you paid for them.
