What would be good alternatives that could replace "participants"?

You could use "contributors" or "partakers". Or instead, you could replace the noun "participants" with "people" or another noun and use phrases like "join in", "pitch-in", and "take part". Within this context, the phrase "take part" and "participants" sound more natural. Ex: We had 12 volunteers pitch in to help set up the party. Ex: There were five contributors at the dinner party last night. Ex: Can the participants for the game please step forward. We're going to start now. Ex: Random people joined in while we were dancing on the street. Ex: 48,000 people took part in 1994.
