domain Is my couple domains worth anything - REDACTED.COM

[Dr.ooz]

I have some domains I bought. I have zero experience with how domains are evaluated or people think it is valuable. Would love to hear your opinion about some of these domains.
1- REDACTED.COM
2- REDACTED.COM
3- REDACTED.COM
4- SHDZONE.COM / SHD.ZONE
5- NEOX.US
6- REDACTED.COM

I don't know if I have something that is worth something or just holding on to garbage.
Let me know are these worth something? How do I know if a name is worth something? or it is just a trend?

SQUADFI.COM = Mid-xxx to low-xxxx

Yep, I thought I might be more since it is squad and just two nice letters FI
