How to describe table in SQL Oracle, I tried desc and describe, but it says desc not supported. I also tried mysql syntax show columns from table, but show is also unsupported?
You don't say what UI you are using, but DESC works in all of them that I know of. If it doesn't
SELECT * FROM ALL_TAB_COLUMNS
WHERE TABLE_NAME = 'MY_TABLE'
AND OWNER = 'MY_SCHEMA';
is an alternative for getting the same information.

How does one get the first name info from a Users table, which has a first name column?
First of all welcome to the community. I suggest you read the guidelines on how to properly ask a question here and you might want to write a title that is relevant to your question.
Now to the question:
Assuming tblUsers is a table in your database and 'first_name' is a column in your table, you can use SELECT followed by the column you want to select.
Lastly, add FROM to select which table you want to select from.
So in your case it would be:
SELECT first_name FROM tblUsers;

oracle query is not working. Please specify what is wrong in this query?
(select hacker_id,challenge_id, max(score) as soc
from submissions
group by hacker_id,challenge_id
having max(score)>0) t2;
Please read #OldProgrammer comments. Anyway, I think this should work for you
select hacker_id,challenge_id, max(score) as soc
from submissions
group by hacker_id,challenge_id
having max(score)>0;

I have about 1000 entries in table. It's simple table with 10 columns. Query:
SELECT * FROM my_table
server runs the query, but is processing it for a long time.
P.S. I know this is not enough info, so please comment and I will add what is needed.
Got it. Not related to SQL. Server got overflown by data. Someone was spamming it.
You can try to use TOP. For example try to select 100 rows and look if server still stucks:
SELECT TOP 100 * FROM my_table
