Yep, we can definitely help.
Can you go into a little more detail though.

I'm just a little confused about whether you're talking about actual barre (bar) chords or not.

For instance, the A Major barre chord is the same as the G Major, F Major, B Major etc etc.. all you do is move the same shape up and down the fretboard.

I'm puzzled as to how you're able to play all but the A Major.
If you already know how to play a B Major barre chord, all you have to do is move it down by two frets and you're playing an A Major barre chord.
