Answer 1

SELECT * FROM sys.certificates
SELECT * FROM sys.dm_database_encryption_keys WHERE encryption_state = 3; -- 3 is encrypted
As mentioned by Erland you can use above queries to find the what databases are using which certificates.
SELECT DB_NAME(database_id) AS DatabaseName ,
Name AS CertificateName ,
CASE encryption_state
WHEN 0 THEN 'No database encryption key present, no encryption'
WHEN 1 THEN 'Unencrypted'
WHEN 2 THEN 'Encryption in progress'
WHEN 3 THEN 'Encrypted'
WHEN 4 THEN 'Key change in progress'
WHEN 5 THEN 'Decryption in progress'
END AS encryption_state_desc ,
create_date ,
regenerate_date ,
modify_date ,
set_date ,
opened_date ,
key_algorithm ,
key_length ,
encryptor_thumbprint ,
percent_complete ,
certificate_id ,
principal_id ,
pvt_key_encryption_type ,
pvt_key_encryption_type_desc ,
issuer_name ,
cert_serial_number ,
subject ,
expiry_date ,
start_date ,
thumbprint ,
pvt_key_last_backup_date
FROM sys.dm_database_encryption_keys AS e
LEFT JOIN master.sys.certificates AS c ON e.encryptor_thumbprint = c.thumbprint
