Welcome to NamePros @Vetra
Selling most domain names is not like selling almost anything else (perhaps original artwork comes close). What I mean by that is that most domain names, even decent one, will go unsold for a very long time. The typical sell-through rate is 1%, so if you had for example 10 domain names, odds are you would sell one domain name by the end of holding them all for 10 years.
Now there are things you can do that may increase your chances of a name selling. As @VivifyDomains
mentioned, by making them all Make Offer and someone needs to communicate with an agent just to get a price, some potential buyers will be turned off.
Also, depending on where they are registered, if you do set a price you could activate Fast Transfer at Afternic. The key advantage of this is that you get in the registration stream, which provides another way that people might find your domain name. Afternic/GD have a number of partners, mainly registrars. If I was on one of those registrars and searched say for a name with sketching in it, then it might suggest as an option your name, and it would be an instant purchase, put in cart and pay for it. Definitely some names sell this way.
Last fall I looked at Afternic Fast Transfer and Sedo MLS, that works similarly. You may find this article helpful:
For one or two of your domain names, a brandable marketplace (like BrandBucket, SquadHelp, BrandPa, etc.) might be an option. While hard to get listed, and when sell the commissions are higher, they do bring a steady set of eyes that are actively looking for a name.
A name like puury might be a good candidate. Perhaps simplified brand logic though suggests that in general one should stick to one change from obvious spelling. If we view the root word as purey, then we have an extra u but also a missing e. Nevertheless, it is short, and the idea of pure can be applied to many sectors, some of them strongly growing.
