You can route-map to match ip address (using ACL) and set the metric. In your topology, try the below:
On R2,
access-list <R4-Prefix> permit <R4>
route-map OSPF-to-EIGRP
match ip address R4-Prefix
set metric <lower-metric for EIGRP>
route-map OSPF-to-EIGRP
set metric <Higher Metric>
router eigrp <>
redistribute ospf <>
on R1,
access-list <R5-Prefix> permit <R5>
route-map OSPF-to-EIGRP
match ip address R5-Prefix
set metric <lower-metric for EIGRP>
route-map OSPF-to-EIGRP
set metric <Higher Metric>
router eigrp <>
redistribute ospf <>
