Embroiderclothing.com - The companies that embroider clothes won't spend good money on this domain, because it won't help their business model much. So, low value domain.
Embroiderclothes.com - As above.
Notebookslcd.com - Low to no value. It just won't help sell something, it doesn't make a lot of sense.
Cryptographycourse.com - Very if not impossible to sell. Extremely niche, and a business running cryptography courses doesn't require it to make money, so won't pay for it. Low value.
Seolinkservice.com - Too generic. Very forgettable. Not brandable. Low to no value.
Sorry if that seems harsh, but it's an honest opinion.
The kinds of generic domains you have registered no longer offer any value to businesses. The domain market has moved on.
Good luck though!
