仮定法は「～ならよかったのに」「～だったら」（日本語でも過去形ですね）なので、時制が過去になります。

あとは、元々の「事実」表現の時制によって
　現在→過去形
　現在完了（完了、継続、経験）→過去完了
になります。
「現在形」か「完了形」かは、「仮定法」とは別の話です。
「分かる、分からない」ではなくて、「そう言うか、言わないか」だけの話です。

(1) 事実（ニュース）は現在のこと。
I would be glad if the news (is) true.

(2) 「時間がある」のも仮定（事実は時間がない）なので過去形。主節は「書き上げた」の意味の現在完了の過去形。意味的には「If 文」も現在完了だけど、「I had had ～」とはあまり言わない。
If I (had) more time, I could have written a nicer project proposal.

(3) これから未来のことの仮定。
If you (would) have any questions, please call me anytime.

(4) ここでは「be to do」で「予定、運命、～したい」の過去形。
If I were (to) win 700 million yen in the lottery, what would I buy for you?

(5) 「一緒に行った（経験）」という意味の完了形でしょう。
I wish I (could have gone) to the concert with you last night.

(6) これも「経験」あるいは「継続」の完了形。
The manager behaved as if nothing (had happened) .

(7) 事実（乗るのか乗らないのか）は知らないけど、乗るとしたらもう出る時間だ、ということ。
It is time that you (caught) the 9:00 a.m. bullet train.

(8) 「継続」（ずっとそこにいる）を表す完了形。
(Had) our supervisor been there, what would he have said?

(9) 「otherwise」の慣用表現でしょう。「さもなければ」「もしそうでなければ」という表現。
主節は「otherwise she would not win ～」というある瞬間の事実の意味でもよいのでしょうが、ここでは「勝利という経験」を言っているのでしょうね。
She did her best, (otherwise) she would not have won the tennis tournament.

(10) ずっと助けられてきた「現在完了」が「もしなかったとしたら」という仮定法。
If it had not been (with) your assistance, I would have failed on this project.
