Typical misdemeanors are trespassing, blocking the road, causing minor property damage or resisting an officer. However, in past mass civil resistance, these felony charges have nearly always been dropped. Prosecutors tend to use them as a scare tactic or bargaining tool. Be aware that the charges which the police write down when they arrest us are not necessarily the charges which the prosecutor uses. The arresting officer's charges are just a suggestion.
Charges are a matter for negotiation using solidarity.
Laws and procedures differ somewhat among the three. Normally, people are prosecuted in the court of whichever entity controls the land where the protest took place. Sometimes, jurisdictions overlap, and we can be prosecuted in more than one court. The various prosecutors get to decide where the case will be tried. Occasionally, one set of activists is prosecuted in state court and another set in federal court during the same campaign.
