I´m not good at explaining stuff, but I can try
chord, you beginn hitting the above ''e'' string and you move downwards to the string at the bodom.
hammer on, let´s say that your playin on string ''D'' you quickly put your finger down on the fret your playing on, for instance
E----------------------------- String 1
B----------------------------- String 2
G----------------------------- String 3
D---5h6---------------------- String 4
A----------------------------- String 5
E----------------------------- String 6
for instance, play on ''d'' fret five, with the index finger, and than you just hammer on the middle finger on fret 6, play on 5, and hammer on 6
pull off, for instance, your playin on string ''a'' fret 7, you just hit that string with your right arm index finger and you pull of, you play on it and instantly just pull off the left arm index finger
E-----------------------------
B-----------------------------
G-----------------------------
D-----------------------------
A---7p(pull off after playing on string)
E-----------------------------
bend, thats the easy part, you just bend the string. For instance, if you playin on ''B'' fret 4, you just bend it, up or down, or both up and down, like this:
E----------------------------- String 1
B-----4^--or--4\/-------------String 2
G----------------------------- String 3
D----------------------------- String 4
A----------------------------- String 5
E----------------------------- String 6
I´m sure you did not understand a bit of that, I understand, after all I´m not that good at explaining stuff
