Do you use #5 without 'the' before 'organize'?
No problem in using?

Answer 1

#1,2,3, & 4 - "to" is unnecessary. "He helped organize the party." "He helped arrange..", etc. Otherwise they are all used and mean the same, more or less. In #6, again, "to" is unnecessary. They all are acceptable. All can be used. To organize the party might imply help with deciding whom to invite, issuing invitations, etc. Preparing for the party might imply setting the table, cleaning the house, cooking foodn and such, but both may include organizational and the practical tasks in getting ready for a party.
