Good news. They should make it just fine until your spring weather arrives. I wouldn't put them outside until then, they need time to acclimate to MA weather.
I can see they are definitely etiolated for lack of proper sunlight. That is why the bottom leaves are pointing down. The offsets need to be planted higher in the containers so they have better air circulation.
I wouldn't waste money on cactus mix, plus the semps don't really seem to like it very much. You can mix very coarse sand with some regular potting mix, maybe 1 part each?, and pumice is good, or chicken grit. You can also place chicken grit under the base of the plants about an inch deep to keep the leaves from touching the soil. When you repot them remove all the dead and soft/mushy leaves. They won't need much in the way of watering until they can go outside.
@JungleShadows Kevin can tell you about when they can go outside, and the best environment for them in MA. He is a master at growing them and started in MA.
Welcome to the group.
Before you know it you will have many different cultivars.
