ASLAAM U LAIKUM PROUD MUSLIM ,
firstly its great to know about your interest in theology in particularly SIKHISM , and sorry for delay in reply .
i will try to answer your question with my little understanding ,
1 Do you believe Sikhism is a successor of the other Abrahamic faiths? I know it is listed as Dharmic religion but the more i read about it, its monotheism and teachings seem very similar to the Abrahamic faiths.
Sikhism is a monotheist way of life , but it differ from ABRAHMIC philosphy .
acc to Sikhi CREATOR IS NO DIFFERENT from its creation but in Abrahmic faiths
creator is in a HEAVEN ,

IN abrahmic faiths after physical death of the body , we will be able to experience / saw GOD .
but in Sikhi this present moment is everything and who is not living this moment wanders insanely

[SIZE=+1]The Shabad alone is Ambrosial Nectar; O Nanak, the Gurmukhs obtain it. ||2||[/SIZE]
2Do you believe Guru Nanak and the following 9 Gurus were also prophets/messengers of God?
my signature says it all, the following lines are also from our Holy text GURU GRANTH SAHIB JI
ਸਮੁੰਦੁ ਵਿਰਲਿ ਸਰੀਰ ਹਮ ਦੇਖਿਆ ਇਕ ਵਸਤੁ ਅਨੂਪ ਦਿਖਾਈ ॥
Churning the ocean of the body, I have seen the incomparable thing come into view.
ਗੁਰ ਗੋਵਿੰਦੁ ਗਵਿੰਦੁ ਗੁਰੂ ਹੈ ਨਾਨਕ ਭੇਦੁ ਨ ਭਾਈ ॥
The Guru is God, and God is the Guru, O Nanak; there is no difference between the two, O Siblings of Destiny:
3Do you believe in Heaven/Hell and afterlife?
Regarding after life Sikh belevive that our aim of life is to became one with lord and one true Sikh reaches the stage where one says " I AM YOU ", regarding heaven /hell GURU says
Kavan narak ki▫ā surag bicẖārā sanṯan ḏo▫ū rāḏe.
[SIZE=+1]What is hell, and what is heaven? The Saints reject them both.[/SIZE]
Ham kāhū kī kāṇ na kadẖ▫ṯe apne gur parsāḏe. ||5||
[SIZE=+1]I have no obligation to either of them, by the Grace of my Guru. ||5||[/SIZE]
Now, I have mounted to the throne of the Lord; I have met the Lord, the Sustainer of the World.
