@Grand Duke,
I think the grammar in these examples holds true in both British and Yank English.
#2 is wrong because it uses the subjective first person singular pronoun "I" as one of the objects of the sentence, when it should only be used in the subject.
(The "subject" is the person or thing or things performing the action in the sentence. The "object" is the person or thing or things to which the action is being done. If the subject or the object consists of more than one person or thing, it is called a "compound" subject or object.)
This is a very common mistake that results, I think, from so many of our elementary school teachers chiding us for saying things like "Billy and me are going out to the playground." Their intent was to teach us that the pronoun "me" should only be used as an object in a sentence, not as a subject, and rightly so. Instead, however, it seems most of us came away thinking there is something inherently wrong with using "and me" in a sentence at all. In fact, it's perfectly correct to say "Sam gave the coin to Jeff and me.", but it is NOT correct to say "Sam gave the coin to Jeff and I".
Luckily for me, at some point one of my teachers gave me this advice: If you want to know if you're using the correct pronoun, break up the compound subject / object into 2 parts and create a separate sentence for each. Ex.
"Sam gave the coin to Jeff and I."
becomes:
"Sam gave the coin to Jeff." and "Sam gave the coin to I." ????
(Does this sound correct? No. Because "I" is being used as an object, when it should only be used as a subject.)
So the 2nd sentence becomes instead,
"Sam gave the coin to me." (That's better)
and the whole sentence then becomes
"Sam gave the coin to Jeff and me."
Now how about "Sam and me gave the coin to Jeff."
This becomes:
"Sam gave the coin to Jeff." and "Me gave the coin to Jeff." ????
This is obviously wrong, so we change it to,
"I gave the coin to Jeff."
And the whole sentence then becomes,
"Sam and I gave the coin to Jeff."
The other rule is to always place oneself last in a compound subject or object. (Think of it as being polite.)
Ex "Sam gave the coin to Jeff and me." NOT "Sam gave the coin to me and Jeff."
and "Sam and I gave the coin to Jeff." NOT "I and Sam gave the coin to Jeff."

You are correct in saying that #4 is correct as it is written in the example.
It would be incorrect to say, "The red white and blue", which I think is the usage that ailsagirl is deprecating.
As for the Americanization of English words, I think it's just a matter of what you're used to. For example, I find it distracting when reading British authors, who use the words "flavour" and "colour" and "honor" instead of "flavor" and "color" and "honor", and who say "Straight away" instead of "right away", and "Right!" instead of "Alright". There are many others. In this case, I think it is just accustomed cultural norms.
And, by the way, I like the English as well. My cousin is married to one, and lives with him in England.
