Yes.
What they call "oil base paint" is really called "alkyd base paint." So yes, you can do that.
Alkyd paint has a resin in it to help the oil in the paint dry faster, oil based paint in my opinion has a more vibrant colors, both in depth an brightness, waterbased seems to be toned down some-what. Wood paint can be either water based or oil based and even water soluble oil based. Oil based alkyd paint lately are used for things or areas that might receive abuse, and because of the slower drying time the oil based alkyd paint will show less brush marks then water based paint.
Not if the melamine paint is oil (alkyd) based.
They can be the same cost. Depends on brand
In the past oil paints referred to either petroleum based paints or linseed based paints. Today in the USA petroleum based paints are no longer sold and it is difficult to find linseed based paints though they do exist with a small proportion of linseed oil. Alkyd paints are made with synthetic oil and are readily available and have come to be known as "oil" paint.
Yes, if the primer is oil-based too (alkyd is good too)
There are different kinds of satin paint - you'd have to know if it was latex, oil, enamel, alkyd etc.

There is no difference. They are one in the same.
Acrylic latex paint is water-based and dries quickly to a flexible finish, making it ideal for interior and exterior surfaces. Alkyd paint is oil-based and has a longer drying time, providing a durable finish that is resistant to wear and tear. Each type of paint has different properties and uses, so it's important to choose the one that best suits your project.
Alkyd is used to create paints that will dry extremely hard and will resist multiple cleanings. Normally, alkyd paints are oil-based, but there are now water based varieties. You can find alkyd paints on doors and trim both inside and outside houses.
I wouldn't recommend it. Some of the chemicals in the alkyd will dissolve the latex and the alkyd won't "stick". It's best to remove the latex using laquer thinner or xylene first.
