Makroohaat of wudhu

Q: Are we allowed to talk to others while doing wudhu? 

Q: If there is bleeding on the surface of the skin such that, if left alone, it doesn't flow, and then one wipes it multiple times and each time new blood fills the surface of the skin without flowing, is this blood impure and does it break wudu?

Note that because it was wiped away multiple times, the amount of blood that was wiped away would have flowed out of the wound, though if the wound had not been wiped, the blood would not have flowed.

Q: Whilst doing compulsory ghusl, you get a cut from a razor when removing hair from private parts and you realise this after few hours only due to seeing some tiny spots of blood on underwear, then is the ghusl and all the namaz prayed valid? Should one repeat the ghusl and namaz? I'm not sure if this was flowing. The tiny spots of blood would equal to a small amount of blood less than a coin however, the spots were scattered over an area of the underwear and this area could potentially exceed the coin size.

Q: From the following ibarat it is understood it is totally impermissible to leave the tap open during wudhu. E.g while doing masah of the head. Is this correct?

وفي الدر ويكره الإسراف فيه تحريما لو بماء النهر أو المملوك له أما الموقوف على من يتطهر به ومنه ماء المدارس فحرام اهـ. حاشية الطحطاوي على مراقي الفلاح شرح نور الإيضاح . ( قوله : فحرام ) لأن الزيادة غير مأذون بها لأنه إنما يوقف ويساق لمن يتوضأ الوضوء الشرعي ولم يقصد إباحتها لغير ذلك حلية ، وينبغي تقييده بما ليس بجار كالذي في صهريج أو حوض أو نحو إبريق ، أما الجاري كماء مدارس دمشق وجوامعها فهو من المباح كماء النهر كما أفاده الرحمتي . رد المحتار وَالْكَرَاهَةُ فِيمَا إِذَا كَانَ الْمَاءُ مَمْلُوكًا أَوْ مُبَاحًا، أَمَّا الْمَاءُ الْمَوْقُوفُ عَلَى مَنْ يَتَطَهَّرُ بِهِ - وَمِنْهُ مَاءُ الْمَدَارِسِ - فَإِنَّ الزِّيَادَةَ فِيهِ عَلَى الثَّلاَثِ حَرَامٌ عِنْدَ الْجَمِيعِ، لِكَوْنِهَا غَيْرَ مَأْذُونٍ بِهَا، لأَِنَّهُ إِنَّمَا يُوقَفُ وَيُسَاقُ لِمَنْ يَتَوَضَّأُ الْوُضُوءَ الشَّرْعِيَّ، وَلَمْ يَقْصِدْ إِبَاحَتَهَا لِغَيْرِ ذَلِكَ.
