The U-shaped piece is called a U-jamb seal for '62-'65 hardtop. It's available through most reproduction houses like Classic industries. The second piece that's red isn't sold in colors as far as I know and would have to be painted. It's called a windlace cap for a hardtop. New or old, that piece cracks just looking at it, much less installing it.
The plastic piece to the left of the U jamb seal is a door alignment wedge. You'll find a similar piece on the door. Used on hardtops and convertibles to assist with door alignment. Available at Classic Industries and most other classic car parts outlets.
