Yes, Deneb is larger than Mira. Deneb, a blue supergiant star, has a radius approximately 200 times that of the Sun, while Mira, a red giant star, has a radius about 300 times that of the Sun. However, when considering luminosity and mass, Deneb is significantly more massive and luminous than Mira, despite Mira's larger size.

No, Rigel is actually larger than Deneb. Rigel is a blue supergiant star located in the Orion constellation, while Deneb is a blue-white supergiant star located in the Cygnus constellation.
Deneb is located in the constellation Cygnus and is one of the brightest stars in the night sky. It is a massive blue-white supergiant star that is around 200 times larger than the Sun. Deneb is part of the Summer Triangle, an asterism formed by three bright stars in the sky.
Deneb is a massive supergiant star located in the constellation of Cygnus. It is estimated to be around 200 times the size of our Sun. Its exact size can vary slightly as supergiant stars like Deneb are known to pulsate and change in size over time.
Deneb is significantly brighter than Pollux primarily due to its intrinsic luminosity and distance from Earth. Deneb is a massive supergiant star, which means it emits much more light than Pollux, a giant star. Additionally, Deneb is located about 1,425 light-years away, while Pollux is only about 34 light-years away; however, Deneb's greater luminosity compensates for its distance, making it appear much brighter in the night sky.

Deneb Catalan's birth name is Deneb Keoni Catalan.
Rigel is brighter than Deneb when comparing their apparent magnitudes. Rigel, a blue supergiant in the constellation Orion, has an apparent magnitude of about 0.18, while Deneb, a white supergiant in the constellation Cygnus, has an apparent magnitude of around 1.25. However, Deneb is intrinsically more luminous than Rigel, but its greater distance results in a lower apparent brightness when viewed from Earth.
Deneb Catalan is 6'.
If Deneb and Rigel were placed at Alpha Centauri's distance from Earth (about 4.37 light-years away), they would appear as extremely bright stars in the sky, similar to our Sun. Deneb, a distant supergiant star, would still shine brightly but not as brightly as the Sun. Rigel, a blue supergiant, would appear much brighter than Deneb due to its larger size and luminosity.
Deneb is a bright blue-white star in the constellation Cygnus.
This is the order from smallest stars to the biggest stars: Alpha Centauri, Procyon, Vega, Pollux, Polaris, and Deneb. These are the size(diameter) of them; though the size of the stars are not 100% accurate so they are likely to be predicted. Alpha Centauri is 1,527,000 Procyon is 2,652,000 Vega is 3,827,000 Pollux is 11,617,000 Polaris is 44,217,000 and Deneb is 203,000,000
