How to determine Initiative for a summoned character?
Go to the source! The PHB (p. 189) says: 1. Determine surprise. 2. Establish positions. 3. Roll initiative. Everyone involved in the combat encounter rolls initiative, determining the order of combatants’ turns. 4. Take turns. 5. Begin the next round.
How to determine Initiative for a summoned hireling?
Any summoned monsters, or hirelings take the initiative order of the player who summoned/hired them. All monsters go during the DM’s turn.
