Not anymore, since Lehi City took over from Utah County. The park is now only open for camping from April 15 - October 15th. Cost is $25 per night. The camp host can no longer accept cash. Reservations are recommended and available online https://www.lehi-ut.gov/recreation/parks/reserving-a-park/ which links to https://lehicitypavilions.sportsites.com/player#Root0
Yes you can. Sorry I don't know the cost.
