Answer :

In the name of Allah, Most Gracious, Most Merciful
Assalaamu `alaykum waRahmatullahi Wabarakatoh
Marriage is a sacred pact in which two people come in a contract to share each their lives together.  The purpose of marriage is not only to fulfill one’s carnal desires in a lawful manner.  This is one of the benefits that are achieved through marriage, but this should not be the only prime focus for getting married.  Also, to issue a divorce for a non-valid reason is also condemned in Shariah. Rasullah (Sallalahu Alaihi Wasallam) has said:
أبغض الحلال إلى الله تعالى الطلاق  (ابو داود)
The most hateful permissible act in the eyes of Allah is Talaq. (Abu Dawood)
 
In another narration Rasullah (Sallalahu Alaihi Wasallam) has said:
يا معاذ ما خلق الله شيئا على وجه الأرض أحب إليه من العتاق ولا خلق الله شيئا على وجه الأرض أبغض إليه من الطلاق (الدار القطنى)
“O Mu’az, Allah has not created anything more beloved to Him on the face of this earth than freeing of a slave.  And Allah has not created anything more hateful to Him on the face of this earth than Talaq”. (Al-Dar Al-Qutni)
Talaq should not be given for just because one’s carnal desired are fulfilled and is not in need of her anymore.  This is a very shameful and low act to commit.
Regarding your queries
The marriage is valid. One of the conditions of marriage is that both parties must be identified; either by looking at them or by stating their name.  In this case, since the person was present, even though the name was false, the nikah will be valid.  The false name will not affect the marriage contract.
Dar Al-Mukhtar, Rad Al-Muhtar (3:26) H.M. Saeed Company
( غلط وكيلها بالنكاح في اسم أبيها بغير حضورها لم يصح ) للجهالة وكذا لو غلط في اسم بنته إلا إذا كانت حاضرة وأشار إليها فيصح ؛ ولو له بنتان أراد تزويج الكبرى فغلط فسماها باسم الصغرى صح للصغرى خانية (در المختار) ( قوله : إلا إذا كانت حاضرة إلخ ) راجع إلى المسألتين : أي فإنها لو كانت مشارا إليها وغلط في اسم أبيها أو اسمها لا يضر لأن تعريف الإشارة الحسية أقوى من التسمية ، لما في التسمية من الاشتراك لعارض فتلغو التسمية عندها ، كما لو قال اقتديت بزيد هذا فإذا هو عمرو فإنه يصح (رد المحتار)
 
It is not lawful for you to marry a girl for the purpose of divorcing her in the future.  This resembles the practice of Muta by the Shia.  However, if he makes nikah with this intention, the nikah will be valid and having this intention does not nullify the marriage.  Even if he had made a contract with her that I will marry you for an X amount time, the nikah will be valid and the condition will be void.  It will be considered a normal permanent marriage.
Fatawa Hindiya (1:283) Maktaba Rashidiya
Rad Al-Muhtar (3:51) H.M. Saeed Company
 
ولو تزوجها مطلقا وفي نيته أن يقعد معها مدة نواها فالنكاح صحيح ، كذا في التبيين ولو تزوجها على أن يطلق بعد شهر فإنه جائز ، كذا في البحر الرائق
(الفتاوى الهندية)
ثم ذكر في الفتح أدلة تحريم المتعة وأنه كان في حجة الوداع وكان تحريم تأبيد لا خلاف فيه بين الأئمة وعلماء الأمصار إلا طائفة من الشيعة ونسبة الجواز إلى مالك كما وقع في الهداية غلط ، ثم رجح قول زفر بصحة المؤقت على معنى أنه ينعقد مؤبدا ويلغو التوقيت ؛ لأن غاية الأمر أن المؤقت متعة وهو منسوخ ، لكن المنسوخ معناها الذي كانت الشريعة عليه وهو ما ينتهي العقد فيه بانتهاء المدة ، فإلغاء شرط التوقيت أثر النسخ
(رد المحتار)

 
يا معشر الشباب من استطاع منكم الباءة فليتزوج ومن لم يستطع فعليه بالصوم فإنه له وجاء  (متفق عليه)
 
“O youth, How ever from amongst you can get married then he should.  If he is not able to then he should fast for verily fast is a shield for him.” (Bukhari and Muslim)

It is a distressing to hear that many Muslims are involved in such sinful acts of deception and playing with Shariah.  May Allah Ta’ala grant them guidance to abstain from such acts, Ameen.
And Allah knows best
