way / method to run two or more sites on 1 instance of a wp-db-plugin

hello and good day,

first of all: i am a big big fan of wordpress!

the question: is there any way / method to run two or more sites on 1 instance of wp-participants-datbase. ( see here full page and info https://www.ads-software.com/plugins/participants-database/ )

And yes: we can take ever other plugin to fulfill this need. So this is a very very genaral question!!

note: i want to run two or more wordpress-sits /(with different topics and genres – e.g. some of the following:

a. jobs
b. talents / artists
c. job-opportnunities
d. volunteering opportunities
…. and others more.

question: can i work and combine all the four sites onto one instlalation of WP-participants-database?!

What I would like to accomplish is to replicate three or four setups with wordpress like I have on my hoste environment, where one, fully independent WP-paticipants-database installation all sit in the same public_html directory and serves the above mentnioed needs.

so the question is the following – is this possible?!

dear buddies, i hope i was able to spell out what i want to achive. If you have any question – just post.

again and above all; i am a big big fan of wordpress. I really love it!!! keep up the great work
