My third finger always touches the 6th string, if I try to push it back to much it interrupts my second finger on the 4th string. I only have learned 3 chord (D , A and E) while I'm able to do D and E almost perfectly(not having any visual or audible problem) the A chord is very hard and very rough. my fingers are average so not too thick that should cause any problem, the guitar itself I'm using is an electric one. Can someone give me some advice that would help me get a grip on the A chord and better finger placement ?
It sounds to me like you need to arch your fingers a bit so they don't lay against the open strings. Try getting your thumb a bit more to the center of the neck and curve your wrist a bit. See section #1 here:
or the postion shown here:
Sometimes, players will wrap the whole hand around the neck to use the thumb to dampen the low E string when playing open A major. In that case you may have trouble keep you fingers off the high E string with a small hand.
If you are just beginning, this hand position may be difficult and your hand will get tired quickly. Give yourself rest. Don't over-do it, but work on it a little every day. Eventually it will be able to do it.
I use two fingers to play an A on an electric guitar, fretting two strings with my index finger.
Also, in some cases you can play A7 as 002020, though this is just avoiding the problem.
In general, there are nice advantages to learning to use one finger to fret more than one string, because it frees other fingers to add different notes to standard chords.
Trying to understand how your fingers are placed! Are you calling the thinnest string 6? We normally call it 1.Your fingers should be nowhere near the 5th string, let alone the 6th! The 5th string (A) is an open string.Some people prefer not to play the bottom string on this chord, as it's not a root chord, but a second inversion. There are many ways to finger an open A.

2nd string ring, 3rd middle, 4th index.
2nd string ring, 3rd index, 4th middle - try it!

one finger across all three, lifting to allow top (1) to ring open.
With a little ingenuity, you'll probably figure out another three or four combinations, proving that there is usually going to be one that works for you. You also need to bear in mind that the chords themselves are only part of the story - you need to be able to move between them easily. So, you may well end up with two or three different fingerings for the same chord shape, dependent on where you come from and where you're going.
