As others have said already, this comes down to common sense.
If the two quotes are from the same source, and appear in that source in the same order in which you are using them, and actually do work together, then you can quote them inline within one set of quotation marks. Whether or not they come from different sentences, paragraphs, or chapters, is pretty much irrelevant as long as the combined quote a) actually makes sense at all in your new context and b) stays true to the original text.
If you are re-ordering the quotes or taking them from two different works by the same author, you should keep them separate — again, in order to stay true to the original(s).
In other words, if the original text by person X says:
I would go with XYZ. It is fine. I like it. It is totally awesome. Blablabla.
Wall of text, wall of text, wall of text.
Wall of text, wall of text, wall of text.
Wall of text, wall of text, wall of text.
Wall of text, wall of text, wall of text.
Wall of text, wall of text, wall of text.
Blablabla. XYZ is absolutely great and does all things.
Then I would argue that it is perfectly acceptable to quote it as follows:
Person X says that XYZ "is fine [...,] totally awesome [...] and does all things".
I don't think that the size of that wall of text matters in the slightest. See it this way: the quote is not actually combined; it is shortened. The author is actually saying those exact things in that exact order. But of course, it would also be fine to write:
Person X says that XYZ is "fine", "totally awesome", and "absolutely great".
This has the additional advantage that you can re-order much more easily:
Person X says that XYZ is "absolutely great", "totally awesome", and "fine".
However, the following, obviously, would not be acceptable:
Person X says, "[XYZ] is totally [...] great".
Lastly, it should be noted that you start your sentence with "Here are a few quotes" (emphasis added). If you actually combine those few quotes into one, you must re-word accordingly. If, on the other hand, you expressly wish to stress the fact that there are several quotes that support your opinion, you shouldn't be in the business of combining them to begin with. Keep them separate:
I would go with XYZ. Person X seems to support my position. He says, "[XYZ] is fine". He also says, "It is totally awesome". Lastly, he even says that it "is absolutely great and does all things".
