Yes. However, there are better ways to write a sentence.

When was she locked out of the dorm?
=> “after she finished her chemical experiment in the midnight” is an adverbial clause.
=> One day, after she finished her chemical experiment in the midnight, she was locked out of the dorm.
=> She was locked out of the dorm one day, after she finished her chemical experiment in the midnight.
** It is redundant to add “one day” in the above sentences.

We have agreed to meet the day after tomorrow.
=> “The day after tomorrow” is adverbial phrase.
=> When have we agreed to meet? The day after tomorrow.


The day after she finished her chemical experiments is her graduation day.
=> In this sentence, “after she finished her chemical experiments” is used to describe “the day”. “The day after she finished her chemical experiments” is a noun clause as a subject of verb.

When will we meet her?
(1) Tomorrow.
(2) When she comes to town.

You can say:
We will meet her tomorrow.
Or replace "tomorrow" with "when she comes to town". To say "tomorrow when she comes to town" is rather redundant,


He sent her roses twice a day before they got married.
Before they got married, he sent her roses twice a day.
=> Like I said earlier, adding "the year" is redundant.

(1) Rain or Shine, ....
=> ("Rain or shine" is an idiom = regardless of the weather)

(2) as it is schedule ( it = meeting)

The correct usage is "NOT enough". It is the one and the only correct way to say it. There is no comparison of which one is more accurate. "NO enough" is simply WRONG.

It is like the word "funner" and "funnest". They are not accepted word usage.

I can't tell you why. It is similar to why you use certain words in Chinese and you cannot explain why.

(1) Probably because "as well as" is a conjunction, so no comma after "as well as". Look at it this way. He, and I, are rich. How does that sound to you? Again, I would say that this is a very awkward and informal sentence and I would suggest rewrite the sentence to: He and I are rich. He is rich, and so am I.

(2)
He is rich as well as I (am).
= He is rich and I am rich too. (His wealth may be higher than mine or the same as mine but we cannot tell from this sentence as it did not reveal the amount of wealth that he and I have)
= Both he and I are rich.
= He is rich, and so am I.

He as well as I is rich. (This is a very awkward sentence. I would not use it when there are better ways to say it. For example: He and I are rich. )

He is as rich as I (am).
= The amount of wealth he has is the same as the amount of wealth that I have.
= He and I are equally rich.

(3)
Treating "as well as" as conjunction, the version with parallel structure is use. I would prefer the version with parallel structure.
=> Personally, I prefer formal English. In this case, treating it as conjunction. I would write it as:
He hurt his arm as well as broke his leg.
= He hurt his arm and broke his leg as well.
= He hurt his arm and broke his leg.

The gerund (-ing form) is used when a verb comes after a preposition:
In this case, some are treating "as well as" as preposition, hence the gerund form.
=> He hurt his arm as well as breaking his leg.

As "they were" requested, I have sent ....
=> they -- the samples

It might be easier to understand if you change the order of the sentence:
I have sent the samples as requested by Fedex with tracking number 123.

Where "it is" possible, I will try to upgrade you to a larger room.
=> it -- to upgrade you to a larger room.

=> I will try to upgrade you to a larger room where possible.

There is a different in meaning.

There is not enough food for them all => We have some food but we don't have enough food to give so that every one of them will have the chance to eat.


There is no food for them all => We don't have any food to give to them.
