The right hand pad is lower on the rim than the left, which is also a bit low. Your right hand arm is moving more than the left, you need to use the v brake adjustment screw at the bottom to even this out, so they both move the same amount. You might need to slightly change that after the end step.
Next move those brake blocks so that they're contacting near the top of the rim at the same point on both sides. Now, adjust the brake lever cable adjuster so it's about half way out and you can move it in. Set the brake cable tension at the brake so the blocks are on the rim and the wheel won't move without effort. Lock it off and release the cable tension at the handlebar so the wheel moves freely. If any part of the wheel is not straight and touches the blocks, use the tensioner screws to move the arms slightly or alternatively, use a spoke spanner to straighten the wheel. This step might need repeating until you get the cable tension correct.
Cheap brakes only need to go out slightly not to work and once the spring tension in the V brakes alters, it all goes a bit squiffy, you might never quite get it right again without replacing the brakes and levers.
