Answer 1

No

Answer 2

No, Eklavya wasn't able to participate in the Mahabharata war because he was killed by Lord Krishna when he came to fight a war against Dwarka.

Lord Krishna showed him respect by seeing his archery skills, even though Guru Dronacharya took his right thumb as guru dakshina, he practiced and mastered the skills of archery without the right thumb.
