Could spinal decompression fix a bulging disk?

Maybe. Some chiropractors use a machine to apply traction to the spine and they call this "decompressioin." the scientific data is not robust so far and I dont believe any insurance companies cover the treatment which can be expensive. Some patients swear that it was helpful while others not so... "caveat emptor".
Depends. The traction machine advertised to "decompress" the spine pulls on it. The disk bulge may temporarily reduce in size during the treatment (pulling the bones further apart), but standing and walking will return the spine to the condition before traction. Bulging is part of the normal aging process and does not always cause pain. The science behind this treatment is soft.

Could spinal decompression heal a bulging disc?

Depends. If you mean getting into a machine and getting pulled into traction there is no good scientific data that supports this. It can be very expensive and insurance companies do not cover it.
Probably not. Spinal decompression is like a large computerized traction machine. The exact mechanism of action is unknown, but likely relieves some pressure off the pinched nerve allowing inflammation to settle. It is very unlikely to heal degenerative "worn out" disk, reversing the changes on mri.

Is it possible for spinal decompression to heal a bulging disc?

Yes. There are definite case reports of patients who have medium sized disc bulges that have healed over time without surgery and with good physical therapy including spinal decompression tables.

Can spinal decompression systems work for herniated or bulging discs?

Non-surgical? If you are referring to non-surgical spinal decompression employed mostly by chiropractors, there is very little evidence showing its efficacy. It is a very costly treatment that uses traction to relieve pain caused by a disc herniation and nerve root compression. It has not shown to be any different then allowing time to allow inflammation to improve.
Do not waste your. Money on a repackaged form of traction. If you want to try something that you can own for a fraction of the price, try an inversion table. There is no scientific literature that supports any spinal decompression system. Bulging discs are not abnormal and herniated disc symptoms may be temporarily decreased with traction.

Is dts spinal decompression therapy the best remedy without undergo an operation to cure slipped disc? Is there any side effects?

Back pain therapy. It is fine as long as symptoms are stable or improving. If pain increases or numbness develops - therapy should stop and you should revisit physician.
Active strengthening. Dts is passive, does not provide longterm benefits e.g. Musculoskeletal strength. It just gives you something to do while your disc recovers. The great majority of "slipped discs" heal up naturally over the course of several weeks, important to do active strengthening exercises. Some feel better while strapped into the dts machine but there is no proof it speeds up recovery.

For slipped disc patients while undergoing dts spinal decompression therapy, is there any supplements recommended to help bones gain more nutrients?

Disc. Is not bone, but to strengthen bone health, you need vitamin d, calcium, exercise and no smoking.
Listen to your body. Dts spinal decompression is an unproved therapy. If one has bone pain with such a therapy reconsider if it is appropriate. Bone pain in young women can be associated with iron deficiency and low 25 oh vitamin d3. Muscle spasm can cause pain and can be relieved sometimes with inexpensive topical magesnium oil.
Supplements. Bones are heavily dependent on vitamin d and calcium. You should have ample supply of both. Often vitamin d levels are decreased and supplemental vitamin d on top of what you get in your diet is recommended. Avoiding alcohol use and smoking are just as important.
