I thought I was feeling pretty comfortable with the differences between the preterite and imperfect but this one has stumbled me.

"He had an English girlfriend" you have translated as Él tuvo una novia inglesa. 

But I would see this sentence as: "He used to have an English girlfriend" (Él tenía una novia inglesa) which would require the imperfect, as it is implied that he no longer has this same girlfriend.

Have I missed something or are both acceptable?

Both seem to mean exactly the same thing. Also, there is only the one 'r' which is causing difference between the two? Can they be used interchangeably?

Should this be "Las Policias" ?? 

d

What is the difference between Camerero and Mesero? Is it something region specific or anything else?

I thought that "Méjico" was regarded as offensive pronunciation of "México."  Isn't that true, or can I use either one of them without being regarded as a vulgar person?

I believe this is the use of buscar in the imperative not the subjunctive. I think this is the informal (negative) command form.   Many forms are the same, but are not from the same parts of grammar.  Subjunctive mood and the imperative mood (commands) are not the same.

Hi, do you have a lesson anywhere that addresses when the subjunctive or indicative is used after constructions like “no dudo que” I was taught they required the indicative, but an example in another lesson called for the subjunctive, and when I searched online I found a lot of personal opinions, but not a good authoritative source. Thanks!

Here is your example from a Kwiziq that prompted me to research more:

No dudo que ________un buen lugar para celebrar la boda. I don't doubt you will choose a good place to celebrate the wedding.HINT: Conjugate the vosotros form of "elegir" in El Presente Subjuntivo.
