Tributes were also paid to Kaveporn Punpare, who had a young daughter and was one of several butlers employed by Mr Vichai.
A statement by his wife said he initially worked as an assistant butler, who accompanied family members on trips, but was promoted in 2015.
She said her husband would be loved and missed by his family each and every day.
Former Miss Thailand contestant Nusara Suknamai was described as a “pillar” of her family.
In a statement, they said: “This is the greatest loss for the family. We will never forget it.”
Leicester City director of football Jon Rudkin also gave evidence to the inquest on Monday afternoon.
He said he walked Mr Vichai to the helicopter, which had landed in the stadium on the evening of the crash, before the chairman waved and gave a thumbs-up as he left in the aircraft.
Mr Rudkin said after the crash, he immediately tried to contact the chairman’s son, who was in Thailand.
He tearfully described the “remarkable impression [the chairman has] made – not only on the football club but on the city”.
“He helped achieve an impossible dream,” Mr Rudkin said. “That was Khun Vichai.”
