If you push the clutch pedal down all the way. Does the noise go away? Or get worse? Or stay the same?

If you push the clutch pedal down just enough to take up the "free play" in the pedal. Does the noise go away? Or get worse? Or stay the same?

Thanks 馃槉

Popping out of 5th gear is usually worn 5th gear synchros and fork inside the transmission.
The iffy shifting in general could be something else.
You say the clutch pedal has a lot of travel.
With the engine off, hold the brake pedal so the car doesn't move, move the shifter through the gears. If it shifts smoothly through the gears the iffy shifting is not in the transmission.
With the engine off, while holding the brake pedal, pump the clutch pedal several times and see if it gets any stiffer. If it does, put the transmission in neutral, start the car, pump the clutch pedal until it's stiff, hold it to the floor and move the shifter into different gears. If it shifts into gears better after pumping the pedal than there is a leak in the clutch master, slave or line.

Sounds like the shift assembly bushings are worn out or missing.
There are two at each end of the change rod. 4 in total.
You will need to replace these before trying to diagnose any other issues with the transmission, worn shifter bushing can cause difficult shifting and incomplete gear engagement.
