Reading the article "How to Introduce People", I (not a native English speaker) found no rules for introducing of two (or more) people. Neither could I find links to the related posts here, on ELL.
Were it I to do the introduction, I'd say, for example:
…, this is Tom Smith, our business partner; and this is Jim Blake, our
lawyer.…, this is Mr. Smith, our business partner; and this is his wife Helen.
I am wondering, if it would be possible and not incorrect to make do without "and this is" here, saying:
…, this is Tom Smith— our business partner, and Jim Blake— our lawyer.
…, this is Mr. Blake–our lawyer, and his wife Helen.
…, this is Mr. and Mrs. Blake, their son Mike, and their daughter Jane.
Maybe I'm over thinking it, or maybe I missed something important, studying English grammar, but more than one and "is"… Well, I've never had the occasion to think about it until just now.
What really confuses me is what if I had to introduce, say, some of my friends to my father? Would it be possible (I myself doubt it, though) to say:
"Dad, this is Tom, Jack, and Sandy, my cronies"?
If it would, wouldn't it lead to:
"Dad, this is my classmates: Tom, Jack, and Sandy"?
(Which is rather confusing compared with "these are my classmates")
This question wasn't spun out of a thin air:
In the digital edition of Collins Cobuild English Usage (para 1.126), I have read that when introducing people, one can use this even when he is introducing more than one person:
"When you are introducing people, you can say 'This is Mary' or 'This
is Mr and Mrs Baker'. Note that you use this even when you are
introducing more than one person."*

Hard as I tried, I couldn't find any other source backing this statement.
In this regard, would it be correct to make introduction like these:
Mom, this is Jane's favorite pupils Pete, Jack, and Andrew.
Sir, this is the two men I've just told you about.
Would someone kindly help me clear that up?

There are a number of things going on in this question. Having read it over a couple of times together with the additional information in the OP’s comments, I think the best way to approach it is case-by-case.
First though it’s worth mentioning that while the OP has pointed out in a number of comments that the question is not about etiquette, it’s not that simple. When dealing with introductions there are established rules of etiquette that we have been trained to follow, whether we do that consciously or sub-consciously is not important, what is important is that they are there and that they do not always sit comfortably with other ‘normal’ usage.
First question – Can we do without the additional ‘this is’?
Generally yes. There are only two exceptions that I can think of; one comes later and the other is where a group is being presented and the person that they are being presented to, often a VIP of some type, makes a comment or asks a question after each name. Think of a royal reception where an elderly Royal makes a politically incorrect statement before moving on to the next embarrassed celebrity. In that case the introduction process resets and you would start again with a ‘This is’
In the same way that I turn to The OED for guidance on etymology and usage, for the definitive guide on matters of etiquette I head to Debrett’s:
As an aside, notice that Debrett’s is very keen that you should always make introductions two-way, completing the above example with “Everyone, this is Mary Brett”
Next, this vs these
OK, this is where it gets complicated.
The general rule is that you follow normal rules of grammar – this for individuals, these for groups
You enter a minefield though when you start dealing with groups that can be thought of as a single entity:
Are both acceptable.
Finally we come to couples and here all the rules change, or rather, they fall apart. Mary Bryant, a writer on weddings and general etiquette starts with the following:
We’ve gone back to an additional ‘this is’….
However, it is also common practice to introduce a couple as a single entity - The reference found for ‘this is’ in Collins is correct in this instance
Although….
I started off by saying that we can’t ignore etiquette and I stand by that. But etiquette, like dialect is only another form of usage, another set of rules – confusing and often contradictory.
