Something is missing from your question. Cygni is not a star. The constellation name is Cygnus. The star will have a name like Alpha Cygni or 25 Cygni.
61 Cygni is a binary star system in the constellation Cygnus.Both stars have a spectral type of K, which means there temperature is around4,500 K. This is cool for a star.See related question for the hottest star.
There is no star with the "F Cygni" classification since there is no exact Greek letter correlation.Zeta Cygni A is an expanding star with three times the mass of the Sun and 15 times its radius, and radiating at 112 times the Sun's brightness. It is fusing helium and has a surface temperature of about 4910 K (compared to 5778 K for the Sun).Gamma Cygni (Γ Cygni, aka Sadr) is an even larger star, a supergiant, 12 times the Sun's mass, 150 times its radius, and emitting 33,000 times as much energy. Its surface is only 6100 K, close to the Sun's 5778 K but with a much faster rate of change. It may only last a few million years in its current state.

NML Cygni, is a Red Hypergiant star, currently the largest know, and one of the most luminous in the Galaxy.
The Earth is about 11.4 light years away from the binary system cygni. Cygni is not the name of a star. It refers to the constellation cygnus (the swan), and is used in the names of stars and other objects within that constellation. For example, the system 61 cygni and the star gamma cygni. The constellation doesn't have a single distance from the earth because the objects of which it is made are all at different distances. For example, the brightest star in the constellation, referred to as alpha cygni, is at a distance of 1630 light years, while gamma cygni, the third brightest star in the constellation, is at a distance of about 1800 light years. 61 cygni on the other hand is only about 11 light years from earth.

Which one - there are hundreds of stars in the Cygnus constellation
