how to query multiple junction tables to create 1 record
This answer assumes you can only have one entry per tournament in each of the Winner1Test, Winner2Test, RunnerUp1 and RunnerUp2 tables. You should contrain this with a unique constraint.

SELECT r.TourneyDate,
r.TourneyTime,
r.TournamentID,
w1.Winner1,
w2.Winner2,
r1.RunnerUp1,
r2.RunnerUp2
FROM TournamentResultsTest AS r
LEFT OUTER JOIN Winner1Test AS w1 ON w1.TourneyID = r.TournamentID
LEFT OUTER JOIN Winner2Test AS w2 ON w2.TourneyID = r.TournamentID
LEFT OUTER JOIN RunnerUp1 AS r1 ON r1.TourneyID = r.TournamentID
LEFT OUTER JOIN RunnerUp2 AS r2 ON r2.TourneyID = r.TournamentID


If my assumption is incorrect and each table can have multiple entries per tournament, then you would need to use outer apply (top 1) rather than outer join.
