You need a period in your first one. It should be two sentences. Wrong punctuation means wrong grammar too. In the last one, a period is also needed. However, you can replace it with a semicolon. A dash is better.

1 This house suits me perfectly I have nothing to complain about. This house suits me perfectly and I have nothing to complain about. Better option: This house suits me perfectly and I have no complaints. 2 Please give me money for taxi. Please give me money for a taxi. 3 I hate waking up early in the morning and going to work. This sentence is fine. 4 You should leave all the things here you can't take them on the plane. You should leave all the things here. You can't take them on the plane. Another option: You should leave all the things here that you cannot take on the plane.
