the first
In most sonatas, there are two themes that occur, the first and second subject. These are played and sometimes repeated. Following that there is a section of developement, in which both themes are changed and fused in various ways. Following that is the recapitulation, where the themes are repeated, often with minor variation. A perfect example of this kind of sonata is Schubert's Unfinished symphony, mvt 1. This said, smaller chamber music sonatas have been known to only have one subject, and romantic music sucha as that of Dvorak often had three or more subjects.
He greatly expanded the development section.
The three sections of a Sonata are: Exposition, Development and Recapitulation. Exposition: the musical motifs are introduced (this section is usually played twice) Development: the motifs are manipulated, expanded, modulated Recapitulation: the original exposition is repeated This creates an AABA form.
It's almost the same except that in a sonata rondo form the main theme is stated between each section (like between the exposition and development sections)
Yes, but it's unusual in that the development and recapitulation sections are repeated instead of the usual exposition.
Repetition or return of the opening material later in a composition such as occurs in the recapitulation of sonata form, though it originally was simply any repeated section, such as is indicated by beginning and ending repeat signs.
Ternary form is a common structure which goes ABA - ie. there is a section of music (the 'A' section), then a contrasting 'B' section, often in a different key, then the 'A' section is repeated. Sometimes there is a coda to finish the piece.

DEVELOPMENTAL
He greatly expanded the development section.
It is not certain that any one man "established" sonata-allegro form. It developed organically, over time, from the simpler a-b-a tertiary form. Embellishments on the main theme in the "b" section gradually became the more adventurous development section of the true sonata-allegro. Most of Scarlatti's keyboard sonatas did not adhere to what Haydn and Mozart would have recognized as a sonata-allegro form.

A bridge is not a recognized part of Sonata-Allegro form. In the classical symphony the elements are, 1. Exposition, sometimes preceded by an introduction. A first theme in the tonic key of the symphony is followed by a second theme in the dominant key. The exposition is usually repeated. 2. Development, one or both themes are varied and expanded through several keys. 3. Recapitulation, the exposition is repeated, but both themes are now in the tonic key. 4. Coda, a short section which closes the movement.
I'm not sure what you mean... The form of the sonata is sonata form. Or if you want to get fancy, it's First Movement Sonata-Allegro Form.
