Decades ago when I was in the stages of learning portrait lighting, my mentor made a statement that has stuck with me since . . . he said, "take the subject to the light".
You have certainly done that as your choice of lighting is great.

Your posing is quite good, but you do have to watch for things like cutting limbs off at joints, showing the back of hands flat instead of the more graceful edges, having subjects from straight on frontal view instead of having the body turned slightly, and a few other knit picking things . . . but all in all quite good.

The "portrait pro" treatment on the group shot is a bit over done, especially on the man on which skin softening should not be done as it is very un-masculine. If you did it on the girls individual portraits, it is well done.

The first impact from your images was that they really lack "pop" and badly needed adjustments on the black and white clipping. I did not mind the lower than normal saturation, but in the examples below I did increase it by 10% . . . not a lot. Sometimes I believe we tend to be influenced by television which is mostly over saturated in my opinion.

I am not seeing an over abundance of red on my calibrated monitor, so left it as your original.

Hope this helps.

Great job!!!

(Tried to post adjusted images, but not working.

Weddingguy nailed it with his edits. I'm guessing from your other posts that your screen is probably needing calibrated not just for color, but brightness. If your monitor is set too bright, those of us with calibrated monitors will see your uploads as very dark, because you adjust your photos based on the brightness of your screen. I would also venture to guess that if you print your photos, they tend to show up way darker than what you see on your monitor.

I'm not a "run out and spend your money" kind of guy, but calibrating a monitor for photographic work is one of the most important things you can do when you are trying to get actual prints to look good. I'm still old school in that a photo isn't a photo, until it is on paper.
