What format do you want? If you want everybody to play everybody, you'll need 9 rounds. If your players are A…I, you could play 9 rounds as follows, assuming you have 4 tables available:
Cohort: all (9 players, odd number, max. 4 tables)
R01 Table 01 B <> C
R01 Table 02 D <> E
R01 Table 03 H <> I

Match counts by player:
A 8 B 8 C 8
D 8 E 8 F 8
G 8 H 8 I 8
If you want team matches (with teams X…Z), you just play:
R1 X-Y (on two tables)
R2 Z-Y
R3 X-Z
Team matches here can be the regular 3x singles plus 1x doubles, or you can play the major league system (no doubles, five games played).
You can also play the Swiss system, with (say) 4 or 5 preliminary rounds followed by a tournament final.
