Not an expert with the actual readings, but in personal experience: You absolutely can manifest specific things/people, and attract already known people - it's just generally not a good idea even if you think it is at the time. 
Very much a 'be careful what you wish for' situation when you do; usually our ideas of specific people are highly subjective, inaccurate and stem from self-delusion more so than the person's actual character. This not only makes it harder to manifest things related to specific people (as you may be manifesting according to details that are unreliable), but also makes it more likely you won't get what you think you're going to if you successfully manifest.
The times I did so have ALWAYS created larger complications in the future than sticking to general manifestations when referring to people. Specific things or outcomes I've had less problems with than specific people, but the risk of complications is still higher. Than being general.

That shouldn't matter, you manifested that persons personality just as much as you do anything else.

Again I'm stating this from experience, but that experience is both as someone who has repeatedly done so and observed others doing so successfully, unsuccessfully, and failing successfully.

then you shouldn’t be talking for everyone

Yeah meant to say 'only from my experience' but I did emphasize this initially, they asked so
