Not sure how much setting up is allowed, but the following solutions for 1 & 2 works within the framework:
-2$ token on Expand, +card token on Lurker, Prince & Expand in trash
Summoned cards Lurker *2, Highway
Play Lurker gaining Expand
Play Lurker (draw Expand) gaining Prince
Play Highway drawing Prince
Play Prince setting aside Expand
Same as 1, replace Highway by Bridge and add some drawing card.
4 and 5 steps, respectively.
