No, sorry, soft to the touch is mush & rot, & I'm sorry to tell you needs to be thrown out (& is beyond saving).

FYI, these colored top plants are grafted onto the green stalks since they're difficult to grown on their own roots; so it's even less likely than normal that you might save it, sorry).

Thanks Pirate Girl. Sad to hear.

BTW, I just learned how to post a picture, and you can see what I'm talking about. Is there anyway to cut the top off of the bottom stalk and try to save the top?

Here is a link that might be useful:

No need to even look at the pix. Sorry, the answer is no, there's not. I explained this in my response, 2nd paragraph, pls. read it again.

Please read my answer AGAIN, the top is the least likely part to survive (as I stated above).

Well, after looking at the pic, the pink one is likely toast. You may have a chance at rooting the yellow/orange one by cutting it off half way between the rot and the yellow (cheating closer to the yellow) let it callous over and then try and root it. If you try this with the pink one, do it in a separate pot.

The soil you have them in looks quite heavy, what is it?

The soil is the first thing I noticed too. Looks overwatered. Karen might be right. They need to be kept warm and dry. If you cut and repot, (which I agree) plant it in a pumice mix. Water after a few weeks. You got a 50/50 on one and 2/98 loss on the other. If you really have a green thumb go for it. Cactus likes to be dry. It took me awhile to learn this.
