There are tons of combinations.
Apart from the most common ones ( venus-mars etc.) I personally experienced jupiter to be great with compatibility in friendship (and also in romantic relationship for sure!).
In the synastry and composite chart with people I get along with smoothly I usually have many jupiter contacts or jupiter-related contacts (saggitarius, pisces, 9th house etc.).
Jupiter is so much about positive attitude, optimism and growth. So sunny. Such a beautiful planet.
