The one to the left is a drift, probably brass, you can see the mushroomed ends from being hit.
In metalworking, a drift pin, drift pin punch, slave pin, simply drift, or even pokey bit is the name for a tool used for enlarging holes, or aligning holes prior to bolting or riveting metal parts together.
