What you have there is a barred rock and three red sex links. They are all female, so good news there.
It's really hard to tell age on the barred rock, she looks like she's just reaching the point of laying. Her comb is large, but looks on the pale side and not especially red and plump. This could be she's young and not quite sexually mature, she's older and getting ready to molt, or she's ill.
I'm guessing it's an age thing since you've not mentioned any illness or acting unusual, droopy, etc. The red sex link hen to the left also has a larger comb, so I'd guess overall they're all just hitting point of lay and you'll be getting eggs within a month from those two. Remember, moving and going to a new home also throws off laying, so that can delay them a few weeks also.
