Help identifying cacti

Migrated topic.

Rising Star
I was hoping someone could help me identify a couple of cactus plants.

Plant 1: 1st and 2nd image. Not sure how old the cactus was when it was given to me. Owned it for a couple of years now.
A pup?-appeared on it near the end of last year (I think).
2nd image shows discolored patches, as if it's been sliced in certain areas and now dried/hardened, is that likely to be from spilling cleaning chemicals over it?
Is this cactus likely to grow any bigger?
I've barely payed any attention to it since I've had it, and I've not noticed any significant growth.

Plant 2&3: 4th, 5th and 6th image.
The second cactus started as just the center, which has now become top heavy and thin/weak in the middle.
Any recommendations for encouraging more growth in this? - or any tips in general on how to handle it? (Edit: went ahead and added a support to it).
Two pups showed up last week and seem to be growing fast.
Third plant doesn't look like the typical cactus, still not sure what it is.

Should they have been replanted by now?

Thanks for any help.

The ones in the first two pictures look like a species of Gymnocalycium.

The 2nd one is going to be really hard to tell without a flower or some more growth.

All those pictures are of the same cactus.
But it does seem that you got the ID correct.
It is so frustrating that many places that sell cacti do not properly label them. I know that most people do not care but for those of us who do it is quite frustrating.

I'll upload the rest shortly. I don't like the fact you have to post a thread before you can attach images. :x

Has this specimen flowered yet?

Not yet, those photos were just taken.

Now I know the species I'll start looking into the specifics, thanks 'Coatl and bufoman. Still a couple more to come.

I meant the cactus in the first two pictures.

Thanks, I believe it is correct. Please take a picture when it flowers and perhaps we can figure out what species it is!
 
Other photos added.

With regard to the first cactus, is it likely to grow any bigger?
He's barely paid any attention to it since he's had it, and he hasn't noticed any growth.

Probably not too much bigger, but it will have lots of pretty flowers.

I think you should replant them if you have had them awhile and they are in the same pots from when you got them.

Ya there is Def. two succulents in the 2nd picture, in the same pot (it appears one is a cactus, the spiny one, and the other is a succulent, not a true cactus).
 
with the skinny ones - the one looks like it could be a t.hausha - etiolated a bit maybe and the other one - swim is 99% sure is not a cactus - more along something of the lines of a wax wick plant - no idea on name.

I don't think it is Trichocereus at all... way too thin and the habit is wrong. Trichocereus normally don't trail like that...

Ya the other one in the same pot is def. not a cactus, it's a succulent!
 
check up coatl perhaps peanut cactus - Echinopsis chamaecereus

i know its not what most trichies look like and i dont think its active - it stays small.
damnit damnit why cant i remember that other ones name - gggrrrr something quadrangularis or something - i will remember :)
 
You wouldn't consider those to be Echinopsis instead of Trichocereus?

What color are the flowers of the above cactus?
 
Thank you all very much for your replies.
Gymnocalycium and Echinopsis chamaecereus definitely seem like the most likely to be out of all I've looked through, thanks again for that.

First thing I'll do is purchase some perlite, cactus soil, coarse sand and organic cactus fertilizer and replant asap. I'm surprised these haven't died yet with the lack of care I've shown them.

I'm curious, what would the effect be of removing the dormant no-watering period (winter) and immersing it in artificial light, heat and continued watering? Good or bad?
 
If you use strong enough lights it will be ok but if they are weak the cause will elongate and/or turn white and look all weird and ugly. It's best to put them in dormancy for the winter.

However... with REALLY strong lights there is no reason why you couldn't do this.
