Pretty sure its a Gymnocalycium and that is a coloration sport of some sort. You must have seen the red and yellow popsicle stick Gymnocalyciums grafted to a green stock. Sorry I can't give the technical name for the coloration sport, but yours has green areas and they will photosynthesize and let your plant survive.

First time with cacti? Other questions? Lots on here can give very good advice.

LB2178 is a Gymnocalycium friedrichii.
From the first photo, I assumed it was degrafted, because it doesn't looks like it has root.
If you planted into the soil without proper roots, with other cactus, and treated it like a normal plant, it probably rot from inside as in the 2nd photo.
You can cut the bottom off, if it wasn't rot, then you can try to root it again on mainly gravel mix, and don't water until it develop some roots.
Unfortunately, from the 2nd photo, the plants probably is too far gone.

Looks like sunburn to me. Variegation on cacti is more sensitive to sunburn than other parts of the plant. It's probably stuffed.

O
So just leave it in the shade ? Or what
And someone said "it's because of poor soil Please keep in cinder base potting mix"

Variegated plants always a bit difficult because they can't photosynthesize properly.
With the poor roots conditions when you got it, it took awhile the roots to regrown.
Means it didn't get any nutrients for many months since you got it. I think that's why it doesn't look well.
Blight but not too much direct hot sun, well-drained mainly gravel potting soil and a bit of fertilizer will help. Keep in mind the weather condition when watering.
As long as there is no rot from the poor root condition you got at the beginning, hopefully it will recover soon.

Since your photo with the roots is current, you need to let those roots callous over before replanting. Let it sit out in a bright area, no full sun, about four days minimum. A week is better. Then repot into your bone dry potting mix. Don't water for a week or more. Then start your watering a little at a time till you see new growth up in the top center of the plant. You'll see new spines starting to grow. No full sun till you see growth, and even then you may want to grow it in a shady area as Bryan said above.

You don't say where you are living. This is an International forum and members are from all over the world. Some are just entering summer while I'm entering winter. Letting us know where you live will let us give you better advice suitable to your climate. You also don't say if you are growing indoors or out. What is your water like? What kind of temperatures do you see over the seasons......

I just looked a little closer at your second photo. It seems like you were growing this Gymno in a community pot with other cacti in the same soil. Is one an Astrophytum? Pots with multiple plants of different Genera are difficult to manage unless all require the same growing conditions. If you are just starting in this hobby, I would get rid of community pots and pot each cactus by itself.

I would not fertilize till I see new growth.

And I'm using just borewell water
There's no much sunlight outside now
Can I place it inside the light chamber where Im using 3w finolex bulb as you have said that to place it in bright area?
Is that enough for plant now?

I'm not familiar with your light and didn't search for it. I'm assuming its an LED light. I am using a 150 watt LED light to grow my 20-30 potted plants over winter. https://www.viparspectra.com/products/xs-series-xs1500 I place plants under the light depending on their light needs. Lower light go to the outside. Higher light go in the center. I vary height by raising the plants and lowering the light.

I can't help with your Astrophytum. I have never grown them. From what I read, they can be tricky. I'll let others comment.

Watch your water for mineral build up. Some people invest in Reverse Osmosis setup to lower mineral content of water.

If I were you I'd edit my profile to add in my location and climate so others can know. Especially if they don't read you are from Tamil Nadu (or if I forget!!)
