Stop. Listen. Every post was out of tune, way sharp. This is not intonation. Intonation is the instrument's build/configuration which can give "good or bad intonation". Mouthpieces can also effect intonation. This is YOU not listening or hearing. You should always be able to hear where your tone is when you play, otherwise it's nearly impossible to play in tune. The sax is an imprecise instrument and even instruments with "good intonation" require us to hear where we are, adjust the mouthpiece to bring your tuning as close as possible (I usually need to retune after just a few minutes playing) and place the pitch where it should be with each note played. To get this really right you need to be your own feedback system of knowing the note you are playing, hearing what comes out of the horn, and adjusting. When you know your horn and yourself it happens without thinking, like driving a car. You are not doing this, and obviously not hearing what you play. The outcome can be something that nobody wants to hear. This is a major killer fault, not an "oh well slipped my mind cause I was thinking of other stuff". If you aren't hearing what you're playing what the heck are you doing?
Seems like I'm not getting through so this is the last post from me on this topic and repeating for the last time: You need to go back to basics and build on solid good habits. You have some very bad habits that need to be broken/retrained. If your teacher can't help you get another, maybe one with a whip (just depends on how badly you want to play well).
