[Solved] (LWJGL) VBO problems

I have a basic triangle in a float buffer.

FloatBuffer vertexData = BufferUtils.createFloatBuffer(amountOfVertices * vertexSize);
        vertexData.put(new float[]{-0.5f, -0.5f, 0, 0.5f, -0.5f, 0, 0.5f, 0.5f, 0});
        vertexData.flip();

And I think this renders it in the gameloop.

glBindBuffer(GL_ARRAY_BUFFER, vboVertexHandle);
            glVertexPointer(vertexSize, GL_FLOAT, 0, 0L);

            glBindBuffer(GL_ARRAY_BUFFER, vboColorHandle);
            glColorPointer(colorSize, GL_FLOAT, 0, 0L);

            glEnableClientState(GL_VERTEX_ARRAY);
            glEnableClientState(GL_COLOR_ARRAY); 
            glDrawArrays(GL_TRIANGLES, 0, amountOfVertices);//what does
            //this do ^? how would i draw another triangle?
            glDisableClientState(GL_COLOR_ARRAY);
            glDisableClientState(GL_VERTEX_ARRAY);

To add more points, I know you increase the number of verticies and add more puts to this.

FloatBuffer vertexData = BufferUtils.createFloatBuffer(amountOfVertices * vertexSize);
        vertexData.put(new float[]{-0.5f, -0.5f, 0, 0.5f, -0.5f, 0, 0.5f, 0.5f, 0});
        vertexData.flip();

But If that does make a second triangle. How do I move only one of them instead of moving both of them. I still don’t fully understand this. Also how do I convert ints to floats for this?
