您好，前两种说法没有问题。对于第三种，我专门搜索了一下外国人的说法，有这么一段表达：
问题：Is “thirty past seven” acceptable?
----- If it is seven thirty, we can also say "half past seven". I am wondering whether "thirty past seven" is acceptable.
回答：It depends what you mean by "acceptable". If you mean
"will native speakers understand me", the answer is yes. If you mean "would a
native speaker say this", then I believe the answer is no. Of course, there are
several dialects that I haven't encountered yet, so one day, I might meet a
native speaker who says "thirty past seven"; but it hasn't happened yet. So it's
probably best if you avoid saying this.
意思是说，thirty past nine英语国家的人能听懂，但平时不会这么表达，尽量避免这样使用。
