Heel-Toe on track

you should always be gentle even when shifting/breaking/accelerating hard dont punch your pedals and dont just drop your foot off. You need to escort all pedals to their resting point not just let go (I hope this is making sense lol English is not my first language) !

underline: Negative on the synchros. Affirmative on the clutch. You've already shifted, the synchro did it's work in the gear change but an over blip or under blip is where the clutch disc comes into play. Remember, you're blipping the throttle with the clutch pedal depressed so over or under-revving doesn't translate to the synchros.

Everytime you shift, you use the synchro. How you shift can put more wear on them of course but synchros, like clutches, are wear items. Heel-Toe or rev-matching in general doesn't elongate the life of your synchros so much as it improves the smoothness of the engine disengaging and re-engaging with the transmissions as to not upset the balance/flow of the car (that lunge you were referring to).

Is it more like predicting what speed range you are going to be in during the initial brake like you said as the weight of the car is transfer to the front then you heel toe according to the speed at that moment? and also I think what you did was you blip after you first shift to the lower gear correct?

Sequential downshifting is easier on the synchros and requires less aggressive blips, but by downshifting twice you risk upsetting the car. By skipping gears you're putting a bit more stress on the synchros, require a more aggressive blip, but since you only downshift once you only risk upsetting the car once. However, missing 2 blips by 500rpm each isn't going to screw you up as much as missing a single blip by 1000+. Play with both ways, there's no "correct" way to do it. Go with whichever upsets the car the least for you, since that is the key.

I honestly can't tell the difference between shifting in sequence. Than just skip a gear. Because in everyday driving there is always cirumdtances where you have to suddenly brake fast rather than the anticipate speed you are going to take a single corner. Say the dumb azz in from of you floor the brake just to take a 25 mph loop. So my speed would drop from 45 in 5th gear to 25... And I am already in the process of turning.

I've always skipped gears on the way down, never any issues doing this. Some pros do, some don't.

There is more than one way, it's not a question of "right" vs. "wrong".
