In grammatical terms, their is a possessive determiner, just like my, your, his, her, its and our. It indicates that what is described in the following noun phrase belongs to, or is in some other way associated with, the person or thing to which the possessive determiner refers. Just as my car is a car that belongs to me, so their house is a house that belongs to them.
There is a word with many uses. In your example, There are lots of skyscrapers in Dubai, it is what is sometimes called a ‘dummy subject’. It would be grammatical to say Lots of skyscrapers are in Dubai, but, generally, we don’t. We use there are (or there is) where French uses il est or il y a, German uses es ist, es sind or es gibt and Spanish uses hay.

word usage - When should I use "there" and "their"? - English Language Learners Stack Exchange
Use of "Their" in a sentence?
When Floowandereeze use their effects to normal summon another card, is the effect of the card that was summoned on a new chain or is it still the same chain as the Floowandereeze?
The "If this card is Normal Summoned:" effects are Trigger effects, so they would activate on the next Chain.

Is there any situation where, if it makes grammatical sense to say ‘they are’ you should use ‘their’ instead of ‘they’re’.
Eg when talking about objects belonging to things.
I’ve always believed that if ‘they are’ makes sense in a position where some would use either there/their/they’re then the correct choice is ‘they’re’. Is this incorrect?

Their means belonging to them, while there is a place or a "dummy subject." In your examples, you would say:
Their house is beautiful.
There are lots of skyscrapers in Dubai.
In the second example, there is a "dummy subject." In the following example, it is a place:
They are in the skyscraper over there.
Is it acceptable to use the word "their" in a sentence such as this one:
"An individual encounters conflicts frequently in their life."
I understand that you can use "his or her" in place of "their", but I encounter these situations constantly and the replacement seems very awkward. The sentence sounds like its right to me, but I am unsure whether it is grammatically correct. Can this issue be clarified?
