Yes, they are, but number 3 would not be heard veryoften, simply because it's not so easy to say smoothly. You need ahard stop between "endure" and "lack," so even if you mean to saythat, it tends to come out as "endure-uh lack."

Q：这两句是否都对？
答：１句对(lack sth.)；２句错（但语法结构并不 错be lacking insth.）.
句２类似结构的关键是 be lacking in + quality
Lacking in courage, he would never leave home.
Totally lacking in charm, he could not attract theaudience.
注：However, this is still not very idiomatic. Iwould expect:
Because he was lacking in courage, he never lefthome.
[注意事项]
1．There is no lack of … 总用is/was单数形式
2．For lack of 里没有the
【问题探究】 He is lack ofmoney.
问：lack 是名词，这里似乎是不能放be动词后的吧？
答：That’swater.名词有时也能用在be动词后。这似乎有些题外了。当然本题句是错误的，下面的都对：
1. He lacks money [lacks = verb]
2. He has a lack of money [lack = noun]
3.He is lacking in money [lacking = adjective]
"He is lack of money." （X）
"He suffers from a lack of money/confidence /personality/etc."("Lack"= noun.) （V）
"I can't meet you today for lack of time."("Lack"=noun.)（V）
"Lacking" 可以是adjective, 常用于be lacking in sth.结构。且那sth.应该是抽象的事物，故上面的句3也错误了。
题目句是错的。可以说: "He is lacking money" 或 "helacks money". 如果说 "He is..." (如 "He is a teacher") 那么就是在描述他什么,也就是他自己不能是(a lack) < he cannot himself be 'alack'>
有时人们把lack用与这样的句子，如 "He lacks common sense/initiative". 'To lack'是个很华丽的古英语动词, 但现在人们也许更可能用 "He has no...".
