I have a welding tank and an oxygen tank and I was wondering If I can fill them with Co2 or Compressed air. To get compressed air do I need to get a scuba tank or is there any other type of tank I can get.

You'll have to find the pressure rating of the tank before you could consider filling it with compressed air. It might be printed on the burst disk and there should be a hydro test sticker or a rating stamped right into the tank surface somewhere. I'd make a guess of 7-8000psi rating for hpa but I would ask a pro at a welding shop for a conclusive answer. To use a tank for C02 the rating would only need to be around 3-4000psi. Again, ask a pro at a welding shop for a conclusive answer. A c02 fill tank will need a siphon installed in the valve to siphon liquid from the bottom of the tank. The tanks will need to be hydroed before someone will fill them for you -
