Yes, it is normal for air to leak down, particularly after a week or so.
And also normal for it to take a few minutes to fill the tanks.
To speed up the air AND to help the engine warm up faster, after it has run for a minute or two, go to high idle (1000-1100 RPM). Read in your chassis manual how to do this, but often the cruise control switches control this.
Also suggest you read up on the air brake system.
