Yes, the sentence is grammatically correct. It is clear and concise.
Yes, that sentence is grammatically correct.
No, it is not.
It is grammatically correct to say , "I am in school today." This is because you are in the building, not at the building.
The word today is a possessive in the noun phrase "today's meeting" (meeting happening today). The word today is an adverb in the verb phrase "meeting today" (occurring today). The latter is unusual but not unseen in sentences such as "The President will be today meeting with his Cabinet" instead of "The President will be meeting with his Cabinet today" especially if there is a longer object such as "meeting the most vocal critics of his plan to end the ongoing crisis" where the "today" could be too far from the verb modified. More typically, the "today" is used to start the sentence.
The word todays is the plural form for the noun today. Example sentence: All of our todays are now yesterdays. The possessive form is today's. Example sentences: Today's plan is for lunch and a movie. Today's date is the twentieth.
It is. In American English, the preferred past tense of cancel is "canceled" with one L, whereas other English speaking countries such as the United Kingdom, Canada, and Australia, the preferred past tense is "cancelled" with two L's. Both are technically correct in all countries and one L versus two is a stylistic choice.
"The men came today to lay the carpet in the living room" is grammatically correct. One could use less words though - "The men came today to lay the living room carpet".
"Let's wear something formal today" is the correct phrase to use when suggesting that a group of people should dress formally. "Let's get into something formal today" is also acceptable but may sound less natural in this context.
"We were informed it will be corrected today" is a correct sentence. However, it might sound a little better to say "We were informed that it will be corrected today."
They didn't have time to have the meeting today so they had to postpone it.
Yeah it's grammatically correct. It is a compound sentence, that is, it has two independent clauses joined by a conjunction or a comma (in this case it's the conjunction "because"). All the adjectival/adverbial phrases are being used correctly, it's all good.
