Remmirath = the Netted Stars, and is commonly identified as the Pleiades. I think this can be included in this 'phase 2' star-making, though not mentioned on the list.
Wilwarin = Butterfly, and I agree is likely meant to be Cassiopeia.
Planets in Quenya include:
Eärendil "Venus",
Carnil "Mars", and
Alcarinquë "Jupiter" and the elves were aware that these 'wandering stars' were different from the others. Obviously no Morning Star yet!

Also, the Sickle of the Valar is Ursa Major, not Ursa Minor, to the best of my knowledge:
Valacirca noun "Sickle of the Gods", a name of the Great Bear (Big Dipper) constellation
(SA:val-, MR:388, KIRIK, OT/OTOS/OTOK)
Telumendil is trickier. My first assumption would be that this is meant to be
Telumehtar, another name for Orion. Otherwise, the name seems to mean 'sky-canopy' which would not be a star or constellation.
Telimbectar ("k") noun,name of constellation:"Orion", lit. "Swordsman of Heaven". Also
Telimectar ("k").
(LT1:268; in Tolkien's later Quenya Telumehtar, q.v. The combination ct is not found in LotR-style Quenya.)
telimbo noun "canopy, sky"
(LT1:268)
telluma noun "dome, copula", especially the "Dome of Varda" over Valinor, but also applied to the domes of the mansion of Manwë and Varda upon Taniquetil. Adopted from Valarin
delgūmāunder the influence of pure Quenya
telumë (WJ:399, 411). Pl.
tellumar is attested
(Nam, RGEO:66).
But Encyclopedia of Arda has this to offer:
Not that Anarríma is any better.
Anarríma name of a constellation: *"Sun-border"???
(Silm; cf. ríma) Ríma means
"edge, hem, border"
Tolkien Gateway is hesitant to identify it:
For anyone interested, there is this 2003 essay on the topic:
