If by "bottom hole" you mean the round hole at the end, then no. Most of the sound of a Flute comes out near where the mouthpiece is
The sound of a flute is made by blowing across the lip plate hole.
What a flute would sound like but an octave higher. (very squeeky)
When you blow across the embouchure hole, the air that goes inside the flute vibrates. When you open a hole, the air is released from being trapped in the flute and goes out of that way. the air that vibrates is sometimes called the air-spring, and the shorter it is,the higher it is.

You blow air over the hole. (Have the flute always rolled more outwards.) If your frown it also helps. Keep trying and you will get it eventually.

a flute
The sound on a flute is produced by blowing quite a lot of air over the hole on the mouthpiece. Flutes have an oval hole over which you must blow. But to do this you must have the right mouthshape, the shape used for spitting rice is appropriate. Then you blow lots of air over the hole. If you blow into the hole, no sound can be produced. But you must blow lots of air, because some of the air escapes when blowing across.
5th hole of the flute
The flute is played by putting the flute next to your chin and blow gently into the hole and pressing keys to make the sound higher or lower.
Not sure what you mean. You're not supposed to cover the embouchure hole, but if you miss an open-hole key or don't cover it well, it will sound out of key and maybe squeak.
The embouchure hole on a western style flute is the hole across which you blow to play. It is on the lip plate which is located on the headjoint.
