Hi Bill.
While a juvenile RTHA like the adult has a belly band, it does not have streaking going up into the chest or into the lower belly. Together with a prominent white superciliary line, I'm inclined to think in terms of American Goshawk, which I think would be rare next to someone's house, unless that house is somewhere in the mountains surrounded by pine woods.
I can't see the tail in any of the except for the second one from the left and there's a suggestion of a longer tail, and theoretically they could be juvenile Cooper's Hawk which has a white superciliary which would be shorter and less prominent. However Cooper's Hawk juveniles have narrow comma-shaped streaks on the breast and unmarked in the lower abdomen, which we use at hawk watches as a distinguishing feature from juvenile Sharp-shinned which has heavier streaks all the way to the lower abdomen, so that species looks 'dirty' in front. These hawks have fairly broad streaks.
All four hawks have feathered tarsi almost reaching their toes, suggesting a more northern raptor like American Goshawk (the name was changed within the past year from Northern Goshawk).
Someone may ask "Why juvenile?" Look at the yellow iris. Most juveniles have yellow irises, compared to orange or brown in adults.
These are my thought processes. I'll be interested in other opinions I can learn from.

This picture was taken by a friend in New Mexico ( I know this is cobirds but NM is close and we have a lot of red-tailed hawks around here!). I have never seen anything like it, it appears to be a group of young red-tailed hawks.
