They were all spread out then we got a bunch of rain and now they are closed up
Research says that if they are in soil that's well drained and not soggy, they should come back just fine. Check your growing conditions and give them a little time. https://www.gardeningknowhow.com/ornamental/cacti-succulents/hens-chicks/growing-sempervivum-plants.htm
Ihave transplanted hens and chickens to a galvanised pot, they seem to be dying.
Were any drainage holes added in the bottom? My concern is root rot from lack of drainage or too much water. If it doesn't have holes, you can plant your hens and chicks in a container with drainage, then set it inside the galvanized pot. Remove the inside container to water it, let it drain, then return to the galvanized pot.
If they are getting soft, go ahead and remove them and move them to a clean pot with drainage. Use fresh potting soil for cacti and succulents. (sometimes the bag says cactus, palms, and citrus).
Hens and chicks need little water; they have fleshy stems that retain water. Here is growing info:

Please help. I have these Hen and chicks from my grandmother in law. She passed away this summer and left me these because I just loved them. She's had them for years. These are her 2 year old babies who have chicks sprouting like crazy. My grandmother in law lived in Arkansas, we live in Montana. This is the same pot she had them in and same soil. The bottom leaves are turning a pinkish brown and shriveling.They are in full sun most of the day if not all of it. I water maybe every 2-3 weeks. So could they be underwatered? Also come winter... What do I do??? It was - 50 for two weeks last winter, surely they wouldn't survive that.. Also I want to split up the chicks, how do I cut them and what soil do I use? Thanks so so much. These mean so much to me and I can't lose them.
You are probably overwatering the hens and chicks. Rainwater should be sufficient unless you go weeks without rain. The article below tells about hen and chick care, soil, etc. When winter comes, I would move them inside or to a garage that stays above 20 degrees F just to be on the safe side. They can take colder weather, but since yours are in a pot, they are more vulnerable.

We have some hens and chicks growing on our front porch. They have been doing very well and have looked healthy. Recently (within last few weeks) some of them have begun showing some white powdery looking stuff on the leaves. Is this something to be worried about? How can I get rid of it before it does damage to the entire planting? I have attached a couple of pictures.
It looks more like mealybugs than powdery mildew. Here is more about how to control them:

All my hens have produced chicks and the chicks have grown from the bottom of mom but I have one hen that has chicks growing from the top of her and some through her leaves
That is strange looking. It reminds me of aster yellows disease or just a plant mutation. Here is more:

It is harmful to them with green plant
I am assuming that you mean "Hens and Chicks". They won't tolerate fertilization, unless it is very, very diluted. They need a rocky, poor, and dry soil. This article will help:

Just wondering what insect or bird would be attracted to the flower of the hens and chicks flowering stalk. Thank you.
Bees are attracted to the flower of hens and chicks.
