fluke dmm, really need help
Shock:
Put a brand new battery in it first!
Second remove the fuses if they are open, it's only for current measurements and that can wait until you have tested the meter properly. So start by closing/shorting the leads on AC, DC, DCmV and seeing what reading you get and if the meter is malfunctioning. Then check the lead resistance and do a diode test by shorting the leads.
If the multimeter has dirty probes or contacts in either the leads or the sockets it's going to throw all your measurements out so it's essential to do this. Next you can read a battery and see if you can get a stable DC measurement or a set resistance on ohms etc and get an idea that the meter is behaving.
Then blow some money on the proper fuses. Let us know how you get on.
Shock:
The neighbor actually did you a favor even though it was a bit of labor on your end. You saved the money on buying the meter. So now you have done all the work you can forget about it.
Here is a video on testing the proper Fluke fuses, you should follow my earlier advice though and see if you have other problems first.

Fuses are supposed to be shorted, that is to say a short circuit, which is to say they should have very little resistance and should beep on a continuity test.
Are your fuses shorted (as they should be), or open circuit (as they should not be)?

The Fluke fuses are special and they're not particularly cheap, but having the correct fuses is important for safety. It shouldn't affect the accuracy of the meter though.

I put a brand new 9V battery in it and it helped a few things like the light, I am only wanting to measure small currents DC and I Will get the correct fuses as soon as i have a chance trust me!

I suppose it must have taken you 2 hours to mow, edge and weedeat both yards. Times sixteen, that's 32 hours of hard labor. Figure 10 bucks an hour (a miserable rate for hard lawnwork) that's 320 dollars in sweat that you paid for that meter. That puts you very close to the cost of a brand-new, fully warranteed Fluke 87-V.

I think this neighbor screwed you.
That being said... let's see if we can confirm that the meter is fully functional at least. First you really do need to get the actual correct fuses, and the guy who enslaved you should really pay for them (they aren't exactly cheap). Once you have the right fuses and a new battery in the thing, we can guide you through some performance tests.

I know, a lot of work, but it was well worth it for how desperatly ive been wanting to get a better meter! I put a new battery and cleaned it up as good as i could, I did a bunch of checks on everything, except current without the proper fuses, I have tried knocking on his door like 5 times since! And my parents could care less to help, I cant really order the right fuses,I have no way to pay or anything, or enough money really!! but trust me I want fuses for it as bad as I wanted the meter!
I will post a picture of the fuses i got for a few dollars from home depot, that i thought maybe effect the current accuracy
