I remember taking such a test a long time back and I came out high in just about everything, well, except probably in Narcissistic and Antisocial.
It does NOT mean you have all those disorders. It just means that according to an unscientific online test, you have many traits of various disorders, but only a professional could diagnose you for sure.
Many of the disorders have lots of overlap with each other in terms of similar symptoms and/or comorbidity (having more than one disorder at a time...though it's highly unlikely to have, say, four personality disorders!).
Just a thought, it's really unlikely to have both avoidant personality disorder or social anxiety and schizoid personality disorder at the same time. People with schizoid personality disorder are usually just fine being on their own and don't tend to seek out friendships, whereas people with AvPD or SA often want friendships (even introverts), but are afraid of being rejected. Schizoid PD, you really just don't care.
Also, paranoia is VERY common with AvPD and SA.
If I don't reply to you, it's NOTHING PERSONAL. It's my ANXIETY.

Det. Devetko: "Definitely."
