The use of Legal Solidarity tactics should not keep anyone from participating in the action. Not everyone can stay in jail. Not everyone can go to court. Give support to those who cannot take part. The strength of solidarity comes from the voluntary agreement of everyone who takes part in it. Just because someone needs to leave jail does not mean that they have "broken" solidarity.
Solidarity is based on consensus and it's easier to reach consensus on tactics and demands if you listen closely to all points of view before launching proposals. This is especially important when working in a group with diverse races, classes, sexual orientations, politics, etc.
You may wish to resist pressure from the police, jail authorities or any lawyers to make rushed decisions. If you're being rushed, bargain for more time. After all, sometimes it has been simpler for the authorities to give another fifteen minutes to come to consensus than for them to carry a bus-full or room-full of limp bodies. (It's a good idea to agree on using such tactics before there is a crisis.)
One problem activists face is that information provided by the police and even lawyers regarding the conduct of other activists is inaccurate. These may include information that all your friends have gone home and you're the only one still in jail, or that it is illegal to refuse to answer questions.
Make sure you base your decisions on reliable information received from someone you trust. When you get separated in jail, you feel really alone and it becomes very easy to believe what they're telling you. This is normal, but stick with whatever decision you made with the group and trust that everyone else is doing the same.
