Actually a blaster is a super heated particles contained coalesced in an energized bolt. A laser is a light wave amplified to emit heat, but I digress.
As for the force push and force wall, if the Jedi had the skill to do so yes he could but think on this. There are many types of ammunition available in a high tech society of the Star Wars universe: Full Metaljacket, Armor Piercing, Incederiary, Armor Piercing Incederiary, Explosive Tip, Glazer, Electro-thermic rounds, Hollowpoint, and so forth and so on.
You have a Jedi with his Lightsaber and a man with a H&K G11 with 4.7mm explosive tipped caseless ammunition. The Jedi sees the man with the very nice slug thrower and goes into battle stance to deflect the bullets. The man goes full auto, expending 50 rounds in one minute. The as the Jedi deflects each bullet explodes against his lightsaber and those bullets that miss him and hit the ground next to him is lighted up by fire and and blown pieces of earth.
One dead Jedi.
