How many piano are in a orchestra?
Most symphonic music doesn't use a piano. Some pieces have one as part of the percussion section, and of course piano concertos have one as well. A few concertos have been written for two pianos.
Mozart composed for nearly every combination of instruments of that time. Examples are works for: piano and orchestra; orchestra; voice and orchestra; piano; string quartet (2 violins, a viola and a cello), string quintet (2 violins, 2 violas and a cello), piano and violin, clarinet and orchestra, flute and orchestra, and many, many others.
Let's just say it's on the list as an instrument available for use in the orchestra. However, the piano is not used on every single piece of written music for the orchestra! The piano will be used only at the direction of the composer - it's the composer who specifies which instrument, and how many of each instruments, are used in his/her composition.

He wrote 5 piano concerti aswell as 2 piano concerti during his youth, one violin concerto which he later transcribed for piano and orchestra and he composed one 'triple' concerto for piano, violin and cello.

The piano is certainly an orchestral instrument, but only from the 20th century (before that it would only play with an orchestra as a soloist). In f.e. Petroushka by Stravinsky it plays an important role. Schostakovich uses piano in many of his symphonies; Bartók, Copland, Falla use it etc. In contemporary orchestral pieces it is very common to include piano in the orchestration.

The piano has never (or rarely) been part of the orchestra, although it has appeared as a solo instrument with the orchestra from around the middle of the eighteenth century onwards. There are works in which the piano is part of the percussion section. A notable example is Stravinsky's ballet Petroushka. When this is the case, the piano is placed behind the strings on the left, next to the standard percussion. This trend started in…
Orchestras are usually tuned to an oboe. The open note, (that is, the note an oboe plays without any fingering), is an A, and the orchestra tunes best to that note. When a piano is featured as solo instrument, the orchestra tunes to the A of the piano, because it's easier for them to adjust their pitch than for the piano.
