I want to get list of all users along with the roles that are assigned to those users in a single query in snowflake.
SHOW GRANTS TO ROLE1; --> This gives me list of all users assigned to ROLE1
BUT I Cannot do something like below -
SHOW GRANTS TO ROLE1
UNION ALL
SHOW GRANTS TO ROLE2
UNION ALL
SHOW GRANTS TO ROLE3;
Objective is to achieve something like above in a single query of snowflake.

I wrote a blog post here that explains how to get the role hierarchy (list of roles in which each user is a member) and effective privileges (a complete list of privileges per user for all grant types). I think the first query may be closer to what you want, but I'm including both:
-- The data returned by both queries is in the
-- SNOWFLAKE database, which has latency of up
-- to 3 hours to reflect changes
-- Get the effective role hierarchy for each user.
with
-- CTE gets all the roles each role is granted
ROLE_MEMBERSHIPS(ROLE_GRANTEE, ROLE_GRANTED_THROUGH_ROLE)
as
(
select GRANTEE_NAME, "NAME"
from SNOWFLAKE.ACCOUNT_USAGE.GRANTS_TO_ROLES
where GRANTED_TO = 'ROLE' and
GRANTED_ON = 'ROLE' and
DELETED_ON is null
),
-- CTE gets all roles a user is granted
USER_MEMBERSHIPS(ROLE_GRANTED_TO_USER, USER_GRANTEE, GRANTED_BY)
as
(
select ROLE,
GRANTEE_NAME,
GRANTED_BY
from SNOWFLAKE.ACCOUNT_USAGE.GRANTS_TO_USERS
where DELETED_ON is null
)
--
select
USER_GRANTEE,
case
when ROLE_GRANTED_THROUGH_ROLE is null
then ROLE_GRANTED_TO_USER
else ROLE_GRANTED_THROUGH_ROLE
end
EFFECTIVE_ROLE,
GRANTED_BY,
ROLE_GRANTEE,
ROLE_GRANTED_TO_USER,
ROLE_GRANTED_THROUGH_ROLE
from USER_MEMBERSHIPS U
left join ROLE_MEMBERSHIPS R
on U.ROLE_GRANTED_TO_USER = R.ROLE_GRANTEE
;

select * from EFFECTIVE_ROLES R

A number of queries in snowflake are not really queries, so you have to fetch the results in an extra step using result_scan(-N) to fetch them
show grants to ROLE accountadmin;
show grants to ROLE sysadmin;
select * from table(result_scan(-1))
union all
select * from table(result_scan(-2));
works for me as you want...
More easy solution:
SELECT ROLE_NAME FROM SNOWFLAKE.INFORMATION_SCHEMA.APPLICABLE_ROLES
START WITH GRANTEE in(select distinct ROLE from SNOWFLAKE.ACCOUNT_USAGE.GRANTS_TO_USERS GTU
join SNOWFLAKE.ACCOUNT_USAGE.USERS u on u.name = GTU.grantee_name
where GTU.DELETED_ON is NULL AND not U.DISABLED AND not
U.SNOWFLAKE_LOCK and U.DELETED_ON is null and U.LOGIN_NAME ='USER' )
CONNECT BY GRANTEE = PRIOR ROLE_NAME
