I think OP means the other two users want to be admins on his/her wiki. I think you should wait more than a few days before giving them privileges, unless you know them from elsewhere, but that is up to you. You could give them other rights first, such as rollback permissions or a moderator role, by visiting Special:UserRights on your wiki.
