Wa aleikum, a-Salam wa rahmatullahi wa baraketuh,
I don't know in what manner you are asking ? I did not analyzed passages of Isaiah 60, 62, but I encourage you to do your own research. If you are interested in Old Testament studies, then it is advisable that you should learn Hebrew, since without it you could be easily refuted by any person influent in Hebrew.
As to the Four Servant Songs, only Isaiah 52:13-53:12 has been identified as a "Suffering Servant". Early Jewish tradition from 200-500 A.D. apply this to the Messiah, but obviously they did not meant Jesus pbuh, since they have already rejected him. I personally do not understand this weird Jewish view of many messiahs. If there were indeed many messiahs, Allah would mentioned other than Jesus (pbuh). Even from the hadith, we do not heard of any Messiah beside Jesus (pbuh), so I think that, since Jews had such a powerful Kings like David (pbuh), after Babylonian exile, they started dreaming about a perfect Kingly Messiah, who will be a king, a priest, and a warrior-prophet, and who will be a saviour to them. When Jesus (pbuh) came, they were deeply disappointed, because he was weak, he did not like to fight, nor had some special authority etc. and after his ascension, they still have this weird idea about a Kingly Messiah (ironically even Muslims sometimes are forced to use it when they want to refer to Prophet Muhammad pbuh as a last of many messiahs). Therefore, I think that this whole concept about many messiahs - Royal and Priestly Messiah - is merely a Jewish joke, a wishful thinking, a pious hope... In other words, if it would be true, I 'am sure that Allah or Prophet Mohammed (pbuh) would have spoke at least one phrase about other messiah - or anointed one - than Jesus (pbuh), but we have nothing, thus it is a Jewish invention !
As to the Suffering Servant from Isaiah 52:13-53:12 it does apply in many ways, but I did not finished my work on this, and it is in early stage of research, but there are some striking allusions which proves that the section of Isaiah 52:13-53:12 is - or was - originally a description of Prophet Mohammed (pbuh), and Allah knows best!
Take care, and salam
