the clutch in the fan is bad. you can spray wd 40 in the back of it but that's temporary. probably need another one.
Sounds like exhaust leak.
Usually it sounds like a clunk. Put the car in drive, step on the brake pedal and hold it down while you slowly accelerate on the gas pedal. If the engine lifts to one side, your mount is broken.
It sounds like your fan clutch is bad.
When you accelerate. you are putting presure on the main engine barrens. if they are going bad. You will hear this knocking sound. I don't know how many miles you have on this engine. But that's what it sounds like. But that's not all that can make this sound. You will have to tell more about it and when it started. Did it just start all at once? or did it start and then get louder?
sounds like your valves are rattling check your oil
Gm used a short piston skirt on this year. The knock is piston slap that normally goes away when engine warms up. Sounds bad, but should not cause any problems.

sounds like your front struts need to be replaced
Sounds like you need a new battery.
Bring to a shop and have it scanned to determine problem
Have the engine scanned for codes. It sounds like a PO300 code. That will be a random cylinder misfire. Cylinder Misfire is nonsense...I have the same problem and the Discovery II workshop manual states that it's a THROTTLE POSTION SENSOR problem that causes the "Check Engine" light to come on and the engine to go into idle. (Hence the inability to accelerate.) Either the sensor is loose or grounded.
sounds like typical transmission problem
