Hello, on the last week's I noticed that the upper leaves close to the pot are falling very easily. I don't know if it's normal. It looks like it's getting bald. Should I be worried? Should I cut the thin dry wires which are coming from the same spot where the leave is attached? I always let it dry a little bit between watering, have drainage, and no direct sun. What to I do to make this grow new leaves all along the branches?

Hedera Ivies have very fragile root systems that do not respond well to repotting or overpotting. When in an overly large pot, it is very difficult to manage the watering properly. If you water yours thoroughly, then the excess soil will take too long to dry out and not allow oxygen in around the roots. The result is root suffocation. On the other hand, if the soil around the roots gets too dry, then many leaves will dry up and fall off.

Attempting to move your plant to a smaller pot now will further stress the roots so I don't recommend that. Water lightly over the soil surface, adding just enough so that the top half-inch of soil is dry again in about a week. This will not be easy to determine but do your best.

Hedera Ivies also need quite a bit of light when grown indoors. Yours should be located very close to a moderately sunny window. Some direct indoor sun is not a problem.

Those are aerial roots growing off the sides of the stems. They have no useful function and cause no harm.

Hedera vines grow new leaves only at the tip ends of each vine. The only way to get new leaves lower on a vine is to cut that vine back. New growth will emerge starting where you make the pruning cut. Pruning does not harm the plant at all, so I suggest you prune many of the longer stems back by at least half their length.

Okay, so less amount of water, more light because now it's a bit far from the window, relocation needed.

Thank you for the directions, just one thing, the parts that I will cut off, in order to get more plants, should i put them in water or in a pot of moist soil? What's better for this plant?

To propagate Hedera cuttings in potting soil, you have to maintain the soil moisture at a constant and near perfect level. It is also best to keep the pot and cuttings inside a clear plastic bag. I think the chances of success are better if you root them in water. Use only tip cuttings from healthy stems. You will have to have a lot of cuttings together to make the project worthwhile.

Hederas are famous for having/getting spider mites.

You can ground-layer the vines to make more. Fill another pot with soil and place it next to this pot. Lay the vines over the soil surface of the other pot and lay a rock on them to maintain contact with the soil. Whenever a root system has formed under the rock, you can sever the connection from pot to pot, and move the 2nd one wherever more is needed.
