Before I dive in, note that there are basic things you should be looking to improve - most importantly,
Scouting
Not getting supply blocked
Constantly making units and SCVs
Aside from that, here's my take on your games.
Game 1
You went straight to Battlecruisers without scouting your opponent. You had no idea if your opponent was expanding, if BC's were a good option vs his unit composition, or where his tech was going after his Reaper opening. Scout your opponent.
Game 2
Once static defense goes down, the bunker rush is over. Spines and Cannons both outrange bunkers. Unless you're still in range of some production structures, pack up and go home. You lost this game because you were pressing an advantage you no longer had.
Game 3
You got lucky this game. Your opponent's hesitation to capitalise on your turtle resulted in you being able to a-move a bunch of Thors into his base for the win.
Your expansion, IMO, went down a little bit late. You put on some good pressure towards the start of the game with your Hellions, but didn't take advantage of this pressure. Expanding behind Hellion harass is a good idea - your opponent will be busy making Roaches, putting down Spines, and making a good show of cowering. If you see you have an advantage, make use of it.
Game 4 Your opponent out-macro'd you. At 14:30 the supplies were 135 to 87 in his favour, allowing him to a-move through your base and win. He out-macro'd you because he was on two bases for most of the game, while you were on one.
If you see your opponent has expanded, you need to do one of two things - be aggressive, or expand yourself. Doing neither allows your opponent to take an economic lead unchecked.
Game 5
You made units and attacked, and your opponent GG'd. Well done.
