I couldn't find "Most players with a 3pt FG in a single game" record. However, I did find a game where 10 players on one team hit 3 pointers. The 11th player on the team tried 5 times but didn't get it to go in. 28 of 59 3pt (19 of 32 2pt). They had twice the number of shots (91 !!) than the other team (30 steals contributed to that). The starters played about half the game. By quarter: 8/19, 7/16, 6/14, 7/10 3FG/3FGA.
Western Illinois vs MacMurray, 136-39
In their next game (against Purdue), they went 4 of 25 for 3FGA. Then 8 of 29 and then 5 of 18.
In the previous season they had at least 2 games with 7 players making 3 pointers.

Three-Point Percent - Season: .495 Jennifer Azzi 1988-89
Three-Point Percent - Career: .452 Jennifer Azzi 1986-90
Something seems amiss. Azzi (1986-1990) is listed as having a career 3FG% of 0.452, with 1988-89 season being 0.489 and the 1989-1990 season as being 0.442. Tara reminded us today that the NCAA adopted the 3pt line in 1988. That makes sense that her career 3Fg% is between those two season numbers. However, Azzi is also listed as having 191 career 3FGs. If she only had those two years, then she must have hit at least 96 one of the years, which would put her at least tied for the Stanford season record in 3FG. Why isn't Azzi listed in the season 3FG category?
And, what about Katy Steding as well? She also had just two years overlap with the 3PT rule. In 1988-1989, she shot 0.446 for 3FG% and in 1989-1990, she shot 0.464. Her career average should be between those two, but it isn't listed in the Stanford records (which go as low as 0.389) or in the NCAA records (which go as low as 0.440). (Azzi is listed in the NCAA records for career 3FG%.) Conceivably, Steding didn't have enough 3FG to be listed in the stats (min 150 3FG).
The 1988-1989 team had a 28-3 record with an average score of 80+. The 1989-1990 NC team was 32-1 with 10 100+ point games and probably averaged close to 90 points. I know Azzi was hitting a lot of 3s.
For the NC game: "Stanford got strong contributions from Sonja Henning (21 points, nine rebounds), Katy Steding (18 points, 6-for-15 on 3-pointers, five assists), Jennifer Azzi (17 points, 4-for-8 from beyond the arc, five assists) and Trisha Stevens (16 points, 10 rebounds)."
