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.
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 Vinegar Doppio from the 37th universe in JORGE JOESTAR. It allows Doppio to turn any ordinary object into a mobile phone which anybody could use. He converts things such as pebbles, rubber balls, shoes, books, a baseball hat, and a lightbulb. The object gets a display and buttons but keeps its original shape. Multiple objects can be converted into phones at the same time. However, once an object becomes a phone, it will permanently remain as one.
When receiving a phone call, the objects ring with a strange ringtone like "Plu pon pin para para pon", vibrate, and an accept call button appears.
The phones are capable of connecting through extremely long distances, as it receives a signal in space and also across different universes and parallel dimensions. However, if there is an inconsistency in spacetime then the phones will not work, such as when England gets transported from the first universe to the thirty-seventh universe while within the giant Antonio Torres's stomach.
Doppio can use the Stand offensively by even turning internal parts of a human into a phone. He transforms a piece of George JoestarO's skull into a phone and then makes the ringtone and vibrations extremely loud, numbing his opponent's brain and harming their equilibrium.
The Stand of Pannacotta Fugo from the 37th universe in JORGE JOESTAR. It is unused and unseen in the novel, but mentioned by Bruno Bucciarati37 when he lists the abilities of all the allies with them. Using the process of elimination, Fugo's Stand appears to be capable of spreading mass delusions to large crowds. Coincidentally, there is a concept of mass hysteria in the novel but it is not related to Fugo's Stand since the concept also exists within the first universe.
The Stand of a parrot that was raised together with Pet Shop. It's a remote control type Stand that appears to be able to possess people from afar through some means, though the extent of its ability is currently unknown.
