The international builders code provides specific load bearing details. I would personally go with 2 18" microlams if the wall is 2x4 with a 15ft. opening. If the wall is a 2x6 wall, a triple 14" microlam may do the job, but be sure to ask the provider of the microlams, as they have specific guidelines regarding their lumber as well as a structural engineer certificate that will state the load capacity for microlams over specific distances. Microlams are milled to 1 3/4 inches, so that when 2 are joined, you have the same thickness as a 2x4 wall or 3 1/2". If you join 3 microlams, you should end up with approximately the same thickness as a 2x6 wall or 5 1/4".

That really cannot be answered without looking at the entire set of plans.

A flush beam is a beam that is flush the the surrounding floor or ceiling joists. Often held in place with metal connectors. It could be a steel 'I' beam, lvl, built up wood. It is used when ceiling height is needed to be maintained.
About 5metres(16') but would have to be stress graded timber.

In construction, a joist is a horizontal piece that runs from wall to wall, wall to beam or beam to beam. A joist is essentially considered to be one of the most supporting pieces towards the structural aspect. It focuses in on supporting beams and other pieces in the floor, ceiling and roof.
you should be fine if you are just supporting the load of the floor. If you are putting increased load on the beam to support the roof somehow that could be a problem.
You will have to have an engineer spec that beam for you. You will save yourself time and money by cutting the span with a column.

The beam is a narrow beam of covered wood set a few feet off the floor. You do basically everything you do on floor on it, but in a more limited area.
