Translation:There are two bus stops near the square.
That is not really logical... After 2, 3, 4 (but not 12, 13, 14), we use:
- when noun is feminine, the noun is in genitive singular (две остано́вки), the adjective is in nominative plural (две авто́бусные остано́вки),
- when the noun is masculine or neuter, the noun is in genitive singular (два авто́буса '2 buses'), adjective is in genitive plural (два больши́х авто́буса '2 big buses').
To further complicate the case, when the adjective precedes such a noun, it's always in nominative plural, even for masculine nouns (после́дние две остано́вки 'last 2 stops', но́вые два авто́буса '2 new buses').
This mess is not really logical. In the past, Russian used to have 3 numbers (singular, plural and dual). Dual disappeared, but after numerals it was used so often that people didn't just drop it, they replaced it with forms that sounded similar to old dual forms. For nouns, this was the singular genitive form; for adjectives, this was the nominative plural form.
However, this is really illogical in modern Russian, so this created a tendency to unify all the forms of adjectives. So, people started using «два больши́х авто́буса» (and not *«два больши́е авто́буса») because it seemed logical to use the same forms of adjectives after all the numbers.
Why this hasn't happened for feminine nouns? It could have happened, it was a living process, but then the literary language was created, and it froze the changes in the language. In colloquial language, *«две автобусных остановки» sounds OK, I'm pretty sure I speak like this myself. But in writing, we imitate the old examples. And so in literary Russian, this would be considered a mistake.
Please look for confirmation/further explanation from native speakers on this.
Близко and рядом are adverbs, whereas около and возле are prepositions.
My understanding is that you can say for example, он рядом or школа рядом by itself, to mean "he is near[by]" or "the school is near[by]". But with около and возле and, I think, близко, you have to include a comparative ~object [I'm not sure if "object" is the correct gramatical description?]: "the school is near [to what?]". So школа находится около музея means "the school is near the museum", but you can't just say школа около or школа возле to mean "the school is nearby". Similarly -- школа близко к центру ["the school is close to the centre"]. You can also use рядом in this way: школа рядом с центром.
I'm sure there's more to it than that, especially with regards to nuances in meaning between the words. And I'm a little less sure with regards to близко and рядом.
Also, it may be worthwhile to note that, where in English we would say "near [to]", недалеко [от]", or literally "not far [from]", seems to be more popular in Russian. E.g. "The shop is near my house." --> Магазин недалеко от моего дома.
То, что вы не говорите, не значит, что «не говорят» вообще.
А «ихний», конечно, тоже нормально звучит. Когда ситуация не требует литературного языка, я его использую (чаще в устной речи, но, например, и в чатах оно тоже вполне уместно).
