Why didn't Samuel (A.S.) get a mention in the Qur'an, but Zeid did?

The Qur'an in 33:37 mentions Zayd ibn Harisa by name. > And [remember, O Muhammad], when you said to the one on whom Allah > bestowed favor and you bestowed favor, "Keep your wife and fear > Allah," while you concealed within yourself that which Allah is to > disclose. And you feared the people, while Allah has more right that > you fear Him. So when Zayd had no longer any need for her, We married > her to you in order that there not be upon the believers any > discomfort [i.e., guilt] concerning the wives of their claimed [i.e., > adopted] sons when they no longer have need of them. And ever is the > command [i.e., decree] of Allah accomplished. (Al-Ahzab : 37) And Samuel is mentioned in 2:246-247, but not by name. > Have you not considered the assembly of the Children of Israel after > [the time of] Moses when they said to a prophet of theirs, "Send to us > a king, and we will fight in the way of Allah"? He said, "Would you > perhaps refrain from fighting if battle was prescribed for you?" They > said, "And why should we not fight in the cause of Allah when we have > been driven out from our homes and from our children?" But when battle > was prescribed for them, they turned away, except for a few of them. > And Allah is Knowing of the wrongdoers. (Al-Baqarah : 246) > And their prophet said to them, "Indeed, Allah has sent to you Saul as > a king." They said, "How can he have kingship over us while we are > more worthy of kingship than him and he has not been given any measure > of wealth?" He said, "Indeed, Allah has chosen him over you and has > increased him abundantly in knowledge and stature. And Allah gives His > sovereignty to whom He wills. And Allah is all-Encompassing [in favor] > and Knowing. (Al-Baqarah : 247) Why? After all, Samuel is a great prophet, and he also had the right to be mentioned. And in addition, there are 125,000 prophets, and many of them are great (such as Daniel, Isaiah, Yusha). Why are they not mentioned? And why are the other companions of the Prophet (Abu Bakr, Umar, Ali) not mentioned?
