An uncirculated coin is bought at the time of it's release, in some sort of protective packaging. If it is out of the packaging, it loses it's status as "uncirculated" and becomes "almost uncirculated" (aUnc), ie. it has been handled. If a coin is in such good condition that you have trouble telling whether or not it has been circulated, get a magnifying glass and examine it very closely. A circulated coin will have very small scratches and nicks on the smooth surfaces. Discolouration or a darkening of the coin does not necessarily mean that it has been circulated.
Florin Paraschiv was born on July 2, 1951, in Bucharest, Romania.

The Eireann or Eire (Irish) Florin was first issued in 1928 and last issued in 1968, just prior to Irelands changeover to decimal currency. From 1928 to 1943, they were made from 75% silver and depending on the year, condition and whether or not they have been circulated, could fetch anything from £3 to £450 GBP. From 1951 to 1968, they were made from a copper-nickel alloy and depending on the year, condition and whether or not they have been circulated, could fetch anything from £1 to £35 GBP. A reputable coin dealer will be able to give a more accurate valuation.
There was no "Festival of Britain" Florin minted, you possibly refer to the "Festival of Britain" Crown (Five Shillings). See "What is the value of a 1951 British Crown - Festival of Britain".
This will depend on its date, condition, and whether it was ever circulated. A coin dealer will be able to show you the value in a book.
