Yes trainers can rematch you in Pokemon crystal but you must register there phone numbers to do that but not all trainers will rematch you, wait until the trainers call you they will mention they want to battle again and they will remind you where they are go there and talk to the trainer to battle them again. They can keep calling you for rematches throughout the game don't miss the chance to rematch them.

It is only possible to get Weedle in Pokemon Yellow by either trading it from Pokemon Red or Blue versions, or use the Mew Glitch and battle certain trainers.
you have to battle 50 trainers for the first battle, and 170 trainers for the rematch with the frontier brain argenta
Trainers can be challenged to a rematch in "fire red" by using the item the "Verse Seeker". It will check it all the trainers currently on screen would like to battle. This time they will be slightly stronger than before, so be prepared. The VS Seeker can be very handy when training for a gym battle or the Elite Four.
no
You find them all and then battle them.
