The first hand you saw the straight and still went all-in with a pair.

Second hand again I think you put too much value in your pair, out of position against a raise after the flop. You can't think the raise was on a pair of tens. The only chance to get the 9T out is to bet more pre-flop.

On the third hand you ended up with a nice hand but you have to question calling the all-in without a pair.
