Not sure how much setting up is allowed, but the following solutions for 1 & 2 works within the framework:
1:
-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
2:
Same as 1, replace Highway by Bridge and add some drawing card.
4 and 5 steps, respectively.
