1. The question has been answered a few times already, but has not been answered.

Okay to omit the subject in the sentences like the above (omitting the subject in the second clause), right?
A comma before but is necessary even when the subject is missing?

2. It is coming soon within 2 weeks time.

A comma is necesasry before "within"?
The bolded part is a prepositional phrase?

3. I can translate the parts that may be confusing, mostly from after the info about the policies.

I should probably take out "from"?
A comma before "mostly" is necessary?
Is the bolded part a correct usage of a prepositional phrase?

4. The information about the policies will be released soon enough within a few weeks, a month or two at maximum, so there is no need to wonder about it too much.

A correct usage of a noun phrase as an appositive?

5. It is okay to omit the subject in the sentences like the above (omitting the subject in the second clause), right?

Vs. It is okay to omit the subject in the sentences like the above, omitting the subject in the second clause, right? 

Both sentences are okay grammar and punctuation wise?

Thanks in advance.
