So I have marzocchi dirt jump 2 forks and on the bottom of the right leg (the leg you pump the air into) there is a bolt. I took that bolt out and noticed there was oil inside. It was only about half full. Do I need to top it up? Should I tip all of it out and replace all of it and what should I use. Cheers

Yes, you should replace the oil and keep it at the manufacturer's recommended level. I can't tell you exactly how much that is though because it varies between model year and fork model/travel.

FWIW, the I'm pretty sure Marzocchi used 7.5 weight oil for the Dirt Jumper throughout its existence, so something like Golden Spectro 7.5 (or equivalent) will be fine.

To find out your oil volume, use this tool from Marzocchi.

And when I depress the valve on the forks water sprays out. How can I fix this. Do I refill oil from the top or the bottom of the fork leg? Thanks

Sounds like you might want to just take the bike to a shop as you likely need new seals and a full fluid exchange. The water could just be condensation, but I've never seen that happen in the past. It could also just be thin assembly lube which is what usually comes out of the schrader valve when you bleed the air.

New seal will run you $25-$35 (in the US, not sure in AUS) and labor for a fork should only be between $60 and $90. Not a huge price to pay for peace of mind, IMO.

the rebound adjustments doesn't do anything so i think it needs a service, and also when i ride there is a clunk when i pull up and land could this be the spring hitting the fork stanchions or lower leg?

Your fork's topping out > likely due to no rebound damping > possibly due to low to zero damper fluid. Time to take'er in to your LBS.
