Well, Univers is Univers, although there are different 'cuts' of it, according to which typefounder created it, character widths and body size can vary slightly to get around copyright. You shouldn't have any problem getting hold of a copy of it,
although it should be in a font folder somewhere. The others I've no idea, but there are thousands of fonts out there, and more created every year. You can't have fonts that are half and half, AFAIK, the computer shouldn't be able to recognise it, but things can get corrupted, and fonts can be a minefield of compatability issues, the set that come installed can't be replaced by any old font from elsewhere. The other two look like they might be Japanese or Chinese fonts, so shouldn't be a problem, I wouldn't have thought.
[edit] Just googled the name, and found this:

it seems to be something to do with Corel, but the link might be a help
