That depends on many other factors. What is the beam material? Is the load a point load concentrated in one spot, or is it uniform across the total span? Specing beams is something that should be left up to a qualified person.
With a span of only 8" you can probably use a wood beam, but without a set of plans no one can accurately answer your question.
That is not a simple anwer. It depends on the roof design and how many, and where the load points are, and the material of the beam(wood, metal, composite). See a structural engineer.
These calculations are not difficult, but you must know the load (including the floor weight) that will be carried. And the deflections that the appropriate building regulations allow.
There are a lot of considerations to be taken into account for sizing steel shapes, especially for a residential home. For instance, what are the load imposed upon the beam? How will the beam be supported? What environment will the beam sit in (i.e. high humidity, moisture, vibration)? A licensed professional engineer or architect in your state can better answer this question.
1'*1'
That question cannot be answered without knowing the load on the beam.
What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts

38 feet longIt is not possible to give a definite answer without more detail. The construction and type of roof will determine the load (weight) bearing on the beam, and factors such as wind load and earthquake load, and the way the roof bears on the beam (truss/point load/distributed load) will all affect the sizing.

There are too many variables to consider for your application. You should consult a qualified engineer for this project.
You will also need to include the acceptable amount of deflection in your question.

The maximum height depends on many factors like the snow load, the wind load, the size of the building, etc. Typically residential post and beam frames can be three stories or more. Commercial frames can go 60 or 70 feet or higher.
That really depends upon the load you need to carry and the material that the beam is made of.
