I need help on my shooting technique, i'm left handed and all my groups are at left of point of aim, and the lower right one was shot by a friend, shes right handed, and she groups to the right of POA. what explains this?

Not the most expert opinion you'll get, but I think you are letting your rifle recoil too much. That's why you are to the left and she is to the right.

What gun, caliber, bullet weight are you using with what kind or rest?
 
I see a mix of vertical and horizontal speads so we should start with the shooter. First question, what are you shooting? Gun, cartridge, shooting position, shooting surface, supports, distance.

As to your left of poa problem, my guess without seeing you shoot is to have you focus on your natural point of aim. After setting up a shot, Close your eyes and count to thirty. Open your eyes. Did your point of aim move? Also make sure you get a nice cheek weld on the stock, and make sure that your body is aligned squarely with your rifle. If prone, your left leg and rifle should make a straight line.

I was on benchrest using sps tactical .308, 168gr hornady match handload. 100yards I practiced alot of dry firing and the poa doesnt shift after firepin strike, the trigger is bout 2.5-3lbs very crispy.

You would need to be a gumby to get into this postition:) If you are a right handed shooter, shooting prone your left elbow, left shoulder, leg hip and left leg should all be in line, but not in a stright line with the rflle. A right handed prone shooter should be slightly angled to the left. Closing your eyes for 3-5 seconds works better than 30 seconds and won't leave you gasping for air. Your natural point of aim should be when you are at the bottom of your breathing cycle. You also want to fire the shot after a full but relax exhale.
 
I am going to add that there are some other inconsistencies.From looking at your vertical spread, some are under 1/4" some 1" or more.IMO this looks like some shooting position/rest issues.

Almost thinking something like a sling stud or fore stock position on a bag or bipod or something along those lines.If you can get your vertical spread smaller then the correction for your left impact is easy to correct diagnose with scope instal/adjustments.

you mean horizontal spray? because the picture is 90 counterclock wise

Dry firing is not the best test, though it is a great check. your rifle holding technique may be causing this only under recoil. for example, are you muscling the rifle? is the butt secure in your shoulder pocket? do you have an overly squishy buttpad? What was your support? Bipod, bags? Shooting a bipod off of hard bench rests can be difficult and require a more precise technique. You can try shooting bags. I'm not sure if it is cant because at 100 yards you would have to be holding the rifle all gangsta style sideways to be off that much. If I'm not mistaken, you are 1-2 inches off poa, so cant, while possible is not likely. I think your trigger pull could be a large part of your groups, but not the poa issue, as that is consistently way off to the left. I would normally say adjust your scope for windage, but if your friend gets the same thing but to the right, then technique is the issue for both of you.

I guess I'd look at cheek weld, and how you use a scope. When placing your cheek on the stock, pull back too far so you can see a black ring form that shrinks your field of view. Now align your vision so the black ring is centred in your field of view, and slowly move forward while keeping the black ring centred as you move until the ring finally becomes one with the tube itself. This is where you should develop your cheek weld. Make note of how your cheek feels, how much pressure you've put on it.

I breathe through my nose or mouth not my eyes, but whatever works best for you is fine :D . My suggestion about closing your EYES for 30 seconds is that the natural wiggles in an unnatural shooting position creep up the longer you are not actively adjusting to stay on target. If you are muscling the rifle into position, 30 seconds or longer will show you the change in the point of aim if you do not have a good natural point of aim.
 
I have seen this happen alternating between left and right handed shooters if the parallax is not set exactly for the distance.
Each shooter will group consistently if they have a good weld but the POI can shift due to parallax and slightly different line of sight from opposite sides of the stock.
 
The parallax was adjusted for 100 yard and checked by moving head around, shouldnt be that i guess.
