Cacti identity

[Bonsai2]

A kind friend gave me a pot of Tesco Cacti which are not named.

I would be grateful for suggestions.

I think the upper two might be dead, but the lower green plant is a Gymnocalycium, either mihanovichii or freidrichii, depending on the flower colour.

[ralphrmartin]

Yes, I'm afraid the top two are gonners.

The one on lower left is an Echinopsis, but it could be one of many hybrids, or Echinopsis oxygona.

I agree with Diane about the other one.

[Bonsai2]

Thank you Diane and ralphmartin for your replies.

On further examination, the top 2 are dead so I have repotted the lower ones.

[ralphrmartin]

Actually, I'm now wondering after a closer look, now you have repotted them:

Is the one on the left actually just another plant of the one on the right, with slightly different colouration?

Well, I thought it was a double-headed plant, Ralph...

[MikeT]

I took it as a doubled-headed plant initially, but looking carefully the 2 heads are different -different spines, different ribs, different rib markings. I think the left hand plant is either an Echinopsis or a Lobivia (and the other Gymno as Diane has ID'd). Should be easy once the heads flower...

Hello Mike, Diane and Ralph

I have taken another photo which I hope will make things clearer. It looks to me if the Cacti are joined.
Sorry about the previous one being less clear.

I have no idea as I am also new to this. But I can say they look very nice.

[ralphrmartin]

I think they are the same - left hand one also has "chins" under the spines, making it a Gymnoclycium, and stripy markings typical of the G. mihanovichii / freidrichii group of species.
