Having been recruited by DIO, Mansaku Nijimura had a Stand, but its appearance and abilities are unknown. As a result of merging with DIO's Flesh Bud after DIO's death, he is seemingly unable to use the Stand anymore.
As members of La Squadra Esecuzioni, it's inferred from Pericolo's remarks in Chapter 469 and the diagram in Chapter 470 that both Sorbet and Gelato possess Stands. However, it is not confirmed that they were able to use them properly.
One of the workers mentioned by Polnareff to Team Bucciarati gained a Stand after hurting himself on Meteorite stone in a volcano. During his coma, he made a spark with his right hand, burning a doctor's fingers.
A Stand belonging to Joseph Joestar. While having a vine-like body, it at least has a fully-formed head. The vines appear from his birthmark and wrap around his arms. It appears to have the ability to project vine-like tendrils, not unlike Hermit Purple albeit without the use of the Ripple.
This Stand is only featured in the game Famicom Jump II: Saikyo no Shichinin, where it's used by an enemy simply called Stand User. The Stand allows its user to turn the player into stone with a special punch against anyone his user defeats or is about to defeat in combat. This transformation makes the victims unable to move, however, Stand users affected by it can sense and even talk. This effect can be reverted if the user is defeated. The Stand has neither a name nor a physical shape, but the image of a rock is shown when the Stand User uses it.
The Stand of Kaoru from the The Anatomy Lesson of Dr. Nicolaes Tulp. Its name is unknown, but has the ability to spawn items under Kaoru's skin. In one instance, Kaoru cuts open his skin and gold coins from another country fall out. When used, an aura in the shape of a horned demon appears around Kaoru.
The Stand of an unnamed genius artisan from the Gucci brand, who bound it to a Gucci bag. It is mentioned that three bags with the same ability were made by the artisan, making it possible his Stand can grant its ability to an unlimited number of bags. Anyone can use the bags, even if they are not Stand users themselves. It has the ability to vanish valuable things that the owner keeps in the bag. When the owner of the bag is in trouble, the bag will return the vanished objects in some way (the objects do not appear in the bag, but the owner will recover them in an unexpected event).
Rohan Kishibe's grandmother had one of those bags and gave it to Rohan Kishibe. Rohan, not knowing the ability was due to a Stand, made the Gucci factory fix the bag (probably the artisan unbound his Stand from it), but, after knowing the bag's true nature, the mangaka lamented for not being able to use it anymore.
The series is known for alternating colors between media, the information presented below may or may not be canon.
(Brown, green, and red leather with silver buckles and zippers, brown strap, golden casing.)
The Stand of Petsounds, who was raised together with Pet Shop. It is a remote-control type Stand with no destructive power. It has the ability to materialize rows of punched cards, which can invade someone's body. Once the punched cards enter someone's body, the victim will hear a voice from the past and is forced to reenact a character's actions that sprung forth from that voice.
All of the re-enacted events so far are tied to DIO, possibly because the events come from what the parrot has seen in its memory. Although Hol Horse cannot control his body while affected by the ability, he remains aware of what is happening to him, possibly due to his knowledge of Stands. Once the victim is freed from the event, they throw up the punched cards.
The Stand is capable of affecting multiple targets at the same time.
